The Booking Calendar MultiUser version have 2 types of the users: super booking admin and usual user.

The "first" WordPress admin user by default is "super booking admin" user.

So, firstly after activation of the plugin you have to see the booking panel for that user.

Then you are need to open the "general booking settings" page (this page is available only for the super booking admin users), then expand the User settings section at the right side and set the correct permissions (user roles) for the pages of the booking admin panel. Its required for the new WordPress users possibility to open the admin booking admin panel.

Now, you can create new WordPress user (the role of this user have to be higher or equal to the roles, which you are set at the previous step).

Now, you are need to open the Booking > Settings > Users page (you are have to be logged in as booking super admin user) and make activation of the booking admin panel for the new WordPress user.

Finally, you can log in as new WordPress user, and you will see own booking admin panel for this user. You can create new booking resource(s), configure the settings and insert the booking form(s) of this user into posts or pages, which is created by this user.

Workflow of configuration for do not have access of "Regular users" to Settings page and having unique configuration of booking form / Emails / Payments, as needed from view of super booking admin user.
So in case if you need to configure booking form field for regular user, and after this configuration block access to the settings field, you need to make following steps:
1) Please log in as "super booking admin user". I can suggest that this user have WordPress "Administrator" user role.
2) Open the Booking > Settings General page and set access level to "Settings" page as "Contributor" (or administrator).
3) Create new WordPress User (via standard WordPress admin panel), and set user role for this user as "Contributor" (or other user role, which you was set at point #2)
4) Open the Booking > Settings > Users page and activate booking admin panel for this new user as for "Regular user".
5) Now log in to WordPress admin panel as this specific "Regular user". Configure booking form fields and emails, and all other settings from Booking > Settings menu.
6) Log out and log in as "Super booking admin user". Now change "user role" for this regular user from "Contributor" to "Subscriber".
Now you can inform login and password of "Regular user" to real person.

Now if this user will log in into the booking admin panel (WordPress admin panel), he/she will not have access to the Booking > Settings page, and will have booking form as you was configured previously.

Booking Calendar Business Large

In Booking Calendar Business Large or higher version, you can configure the capacity for the specific booking resource.

The Capacity feature in Booking Calendar Business Large / MultiUser versions provide for you ability to set and manage the capacity for specific resources: properties or services.

Resource-Specific Capacity:
Define the maximum number of bookings or appointments that a specific resource or service can handle simultaneously. For example, if you manage a hotel with a particular number of room types or a meeting room, set its capacity to, say, 10, indicating it can accommodate up to 10 bookings simultaneously. This feature works for full dates or time slots on selected dates.

Real-time Availability Updates and Efficient Resource Management:
As bookings are made, the system automatically updates the available capacity in real-time. If the maximum capacity is reached, the system prevents additional bookings for that resource during the specified date(s) or time slot.
This feature enhances resource management by preventing overbooking and ensuring that each resource operates within its defined capacity limits.

Useful for Various Scenarios:
Ideal for businesses or services with limited capacity for specific resources, such as hotel rooms, specific property types, meeting rooms, tours, classes, or any other bookable items.

Improved User Experience:
Users can quickly see the remaining capacity for a resource when making a booking. You can display available slots in mouse-over tooltips when hovering over a specific date or use [capacity_hint] in the booking form to show available slots on selected dates in real-time.

Example Scenario:
Imagine running a workshop space with a capacity for 20 people. With the capacity feature, you can ensure that once 20 bookings are made for a particular time slot, additional bookings for that time will be prevented.
Alternatively, if you have 10 standard rooms and 5 double rooms in your hotel, you can display two separate booking forms—one for "standard rooms" with a capacity of 10 and another for "double rooms" with a capacity of 5.

How to Use:
Configure the capacity feature in the admin panel at the Booking > Resources page. Set the capacity for each resource individually by specifying the maximum number of bookings it can handle.

1. Parent booking resource.

Open the Booking > Resources page.
Find the booking resource you want to increase the capacity for or create a new booking resource (e.g., "Resource A").
To create a new booking resource, enter the "Name of booking resource" in the top toolbar at the Booking > Resources page and click the "Add New" button.

2. Increasing Capacity:

- Click the "Expand advanced toolbar" arrow button at the bottom left side of the toolbar to reveal additional options.
- Enter the name of the child booking resource (e.g., "Child Resource A").
- Select the number of child booking resources to create (e.g., 5) to set the capacity of the original "parent booking resource" ("Resource A") to 6.
- For the option "Parent" select our parent booking resource - "Resource A".
- Click the "Add new" button in the toolbar to add 5 child booking resources to our parent booking resource "Resource A," resulting in a total capacity of 6 (including the parent booking resource itself and 5 child booking resources).

3. Structure of Booking Resources:

The structure of booking resources will look like this:

Resource A | Capacity = 6 | Priority = 0
        -  Child Resource A - 1
        -  Child Resource A - 2
        -  Child Resource A - 3
        -  Child Resource A - 4
        -  Child Resource A - 5

4. Publish Booking Form

Let's say each booking resource has an ID like this:

[ID=218] - Resource A | Capacity = 6 | Priority = 0
      [ID=219]  -  Child Resource A - 1
      [ID=220]  -  Child Resource A - 2
      [ID=221]  -  Child Resource A - 3
      [ID=222]  -  Child Resource A - 4
      [ID=223]  -  Child Resource A - 5

[booking resource_id=218 nummonths=3]

Learn how to put the booking form or availability calendar on your pages using Booking Calendar blocks in the WordPress Block Editor or Classic Editor on this page .
Also, check the simple steps to add the Booking Form manually to your page with shortcode blocks, for example, in non-standard page editors like Elementor, Divi, or others on this page.

5. Preventing Overbookings:
When you make a booking for a specific date or time, the system will decrease the capacity of the booking resource. If the number of bookings reaches the capacity limit of the booking resource, the date or time slot on the specific date(s) will become unavailable

6. Capacity Control Field:
What if you need to book 2 or more slots on a specific date/time? Define the field that will identify how many slots will be booked during one booking process. Open the Booking > Settings General page in the "Capacity" section, enable the "Booking Quantity Control" option, and for the "Quantity field name" select one of the existing fields from your booking form. This field must be a select box with simple numbers as options. For example, configure the field at the Booking > Settings > Booking Form page like this: [select visitors "1" "2" "3" "4" "5" "6"]. In this case, for the "Quantity field name" select the "visitors" field. Save settings changes.

Now, when you select a date (and/or time) and choose the number of visitors as 3, the system will make a booking of 3 "child booking resources" (or parent and 2 child booking resources) and decrease capacity on the selected date/time by 3 items.

7. Disable Bookings in Different Booking Resources:
An additional option "Disable bookings in different booking resources" at the Booking > Settings General page in the "Capacity" section. This option disables reservations that can be stored in different booking resources. When checked and you select several dates to book, all reserved days must be in the same booking resource; otherwise, an error message will show. For example, if you make bookings for a specific property (room), it prevents changing these rooms during all selected dates. In other words, the system checks that all selected dates in child booking resource (or parent booking resource) have to be available and stores this sequence into the SAME booking resource. Otherwise (useful in some situations), the system can store a booking on DAY 1 in child booking resource A and on DAY 2 in child booking resource B (in case if DAY 2 for the booking resource A was already unavailable).

8. Priority Field:
At the Booking > Resources page, there is a "Priority field" for each of your booking resources. It is the order in which the system will check availability and save the booking into the available child booking resources.

7. Different Capacities for Different Resources:
In a scenario where some booking resources support a maximum of 2 visitors per resource and other booking resources support 4 visitors per resource, you can create 2 different custom booking forms at the Booking > Settings > Booking Form page.

In custom booking form for "Standard Rooms" (e.g., with the name "standard-rooms-form"), you can have these fields:

Visitors number: [select visitors "1" "2"]
Number of rooms to book: [select items_to_book "1" "2" "3" "4" "5" "6"]

Visitors number: [select visitors "1" "2" "3" "4"]
Number of rooms to book: [select items_to_book "1" "2" "3"]

The structure of booking resources at the Booking > Resources page can be like this:

Standard Rooms:

[ID=10] - Standard Room - 1 | Capacity = 6 | Priority = 0
      [ID=11]  -  Standard Room - 2
      [ID=12]  -  Standard Room - 3
      [ID=13]  -  Standard Room - 4
      [ID=14]  -  Standard Room - 5
      [ID=15]  -  Standard Room - 6

Family Rooms:

[ID=18] - Family Room - 1 | Capacity = 3 | Priority = 0
      [ID=19]  -  Family Room - 2
      [ID=20]  -  Family Room - 3

In the page for booking Standard rooms, you can use this shortcode:

[booking resource_id=10 nummonths=2 form_type='standard-rooms-form']

In the page for booking Family rooms, you can use this shortcode:

[booking resource_id=18 nummonths=1 form_type='family-rooms-form']

Defining Cost Per Night/Days/Hour or Fixed Cost

To set the cost per night instead of per day or a fixed cost, follow these steps:

• Navigate to WP Booking Calendar > Settings > Payment Gateways page.
• Scroll down to the Payment Options section and select "for 1 night" for the "Set the cost" option.
• Click on the "Save Changes" button.

Additionally, you can choose from the following variants of defining costs: "per 1 night", "per 1 day", "per 1 hour", or a fixed cost.

Difference in Costs Per 1 Night Instead of Cost Per Day

Here's an example to illustrate the difference:

Let's say a visitor selects 4 dates in the calendar: 2025-04-01, 2025-04-02, 2025-04-03, 2025-04-04.
For the booking resource (calendar), you've defined the cost as $100 at the WP Booking Calendar > Resources page.

If you define the cost per 1 day, the total cost will be $100 + $100 + $100 + $100 = $400.
If you define the cost per 1 night, the total cost will be $100 + $100 + $100 + $0 = $300.
If you define a fixed cost, the cost for all those dates will be a fixed sum: $100.

Relative Cost Per Hour

The cost per hour system calculates the cost based on 24 hours in a day. In our case, it would be:
4 days * 24 hours * $100 = 4 * 24 * 100 = $9600.

At the Business Small and higher versions of Booking Calendar are supported several payment systems integrations.

1) Each payment system support own list of currencies.
So you can change and check the list of the currency at the Booking > Settings > Payment page at the each section of payment system integrations.

2) Also at the Booking > Settings > Payment > General page you can select the currency that is showing in the Booking admin panel and at front-end side (in hints) of the Booking Calendar plugin.

3) In the Booking Calendar Business Medium or higher versions at the Booking > Settings General page in Calendar section, if you have activated this option "Showing cost in date cell", then you can select currency symbol that will be showing in the calendar day cells.

If you need to set different daily costs for different seasons or weekdays, the Booking Calendar Business Medium or higher versions allow you to do just that.

Set different daily rates for different seasons or weekdays to optimize your pricing strategy to seasonal demand or specific days of the week.

For example, you may want to charge higher rates during peak seasons or weekends.

You can set rates as a fixed cost per day (night) or as a percentage of the original cost of the booking resource.

Seasonal Pricing Configuration:

• Navigate to WP Booking Calendar > Prices > Daily Costs page.
• Click on the "Seasonal Pricing" button to access the seasonal pricing configuration.

Seasons Setup:
To adjust days within specific seasons or create new seasons, navigate to WP Booking Calendar > Prices > Seasons page. Here, you can create conditional seasonal filters based on days conditions, or use the Days Season filter to easily select the necessary days.

If you need to set different costs for different lengths of bookings, the Booking Calendar Business Medium or higher versions allow you to do just that.

For instance, you might want to offer a discount for longer stays, like two weeks or more.

You can configure this feature under "Duration-Based Costs" in the WP Booking Calendar > Prices > Daily Costs page.

To learn more about this feature, check out the Valuation Days Overview.
You can also watch a video guide here: Valuation Days Cost Video Overview.

"Duration-Based Costs" work for any day on the calendar, regardless of the season or weekday. However, if you'd like to apply them only to a specific season, you can base it on the check-in day. In simpler terms, this feature lets you offer discounts or adjust costs based on the length of a booking. For example, if a guest books seven or more days, they could receive a 10% discount.

In case if you need to apply it to a specific season, then it can depend only on the belonging "check-in day" to a specific season. It means that, if you select 2 weeks, the "Duration-Based Costs" can apply costs only depending on the check-in day belonging to a specific season, even if some other days belong to another season. In other words, if you will have the days selected with season intersections, then you can have an issue with "Duration-Based Costs".

Let's explore some examples to better understand how to configure this:

Example #1

Let's say the standard daily cost is $100 per day. But if a guest books six or more days, all future days have a cost of $75 per day.

    1st day = $100
    2nd day = $100
    3rd day = $100
    4th day = $100
    5th day = $100
    6th day = $75
    7th day = $75
    ..
    99th day = $75

    From 1st to 5th day = $100 per day
    From 6th to 99th day = $75 per day

Example #2 - Understanding the "Together" Term

If the standard daily cost is $100 per day, and a guest books one week or more, they get a 10% discount. Importantly, this discount applies to all days, not just the seventh day.

For example, if a guest books six days:

		1st day = $100
		2nd day = $100
		3rd day = $100
		4th day = $100
		5th day = $100
		6th day = $100

But if they book seven days:

		1st day = $90
		2nd day = $90
		3rd day = $90
		4th day = $90
		5th day = $90
		6th day = $90
		7th day = $90

Configuration:

    From 1st to 6th day = $100 per day
    Together 7 days = 90% for all days
    From 8th to 99th day = 90% of the cost of 1 day

Example #3 - Costs per Nights

If you're charging per night instead of per day, the configuration from Example #2 would be adjusted accordingly:

    From 1st to 6th day = $100 per night
    Together 7 days = 90% for all days
    From 8th to 99th day = 90% of the cost of 1 night
    For LAST day = $0 per night

Where "LAST" - it's a reserved term that defines the last selected day.

This FAQ guide explains step by step how to set up partial payments/deposits, allowing customers to pay a portion of the booking cost upfront. Later, you can request the remaining balance from customers by sending "payment requests." This functionality is available in the Booking Calendar Business Medium or higher versions.

1. Setup Partial Payments.
To configure partial payments for a specific booking resource, navigate to WP Booking Calendar > Prices > Daily Costs page. Click on the "Partial Payments" button next to the specific resource. Then, enable the "Deposit" payment option and configure the amount of the partial payment. It can be a fixed amount or a percentage of the total booking cost. Partial payments can also depend on the booking's check-in date for specific seasons or the difference between today and the check-in dates.

2. Publish page with booking form.
Now, follow this guide to publish the booking form for your booking resource.

3. Submitting booking and processing partial payment.
In our example from point #1, we have set the cost for the booking resource at $100 per day and defined the deposit cost as 30% of the total booking cost. Let's say we are making a booking for 5 days, with a total cost of $500. In this case, the "Deposit Payment" would be 30% of $500, which equals $150. Check out the example below to see how a visitor makes a booking and submits a deposit payment (partial payment) for it.

4. Booking Notes with Payment Breakdown.
When an administrator checks "Notes" of this booking in the Booking Listing page in the admin panel, they will see the payment breakdown as follows:

  Total Cost: $500.00
  Deposit Due: $150.00
  Balance Remaining: $350.00

Important to note! The booking cost field displays the last cost shown in the payment form. In our case, it was the deposit cost of 30%, which is $150.
Please note, the booking was auto-approved due to the enabled "Auto-approve booking" option at WP Booking Calendar > Settings > Payment Gateways > Stripe page. This occurs when a visitor successfully makes a payment. The same option is available for PayPal and some other payment systems.

5. Emails.
Which emails were sent to users during this time?
It depends on the activated "emails" at WP Booking Calendar > Settings > Emails page.
Visitors may receive the following emails:

• Email notification about the creation of a new booking ("New (visitor)" email template).
• If you activated the "Auto-approve booking" option at WP Booking Calendar > Settings > Payment Gateways > "Specific Payment Gateway" page, the system sends an email confirming the booking approval ("Approved" email template).

6. Sending Payment Requests to Pay the Specific Sum.

To send payment requests, ensure you've set up the [bookingedit] shortcode correctly. Refer to our detailed guide for step-by-step instructions on configuring the [bookingedit] shortcode.

To send payment requests for paying (in our case) the remaining balance, edit the booking's cost in the "cost field" and click on the "Save cost" button. In our example, we changed the cost from $150 to $350. This is a manual process.

At this point, the system can send a "Modified" email to the user. After changing the cost for a booking, the plugin can automatically send a notification email to the visitor if the following conditions are met:

• Ensure that the "Emails sending" option is enabled under the Filter toolbar.
• Activate the "Send email on cost changes" option at WP Booking Calendar > Settings > Payment Gateways page.

If both conditions are met, the plugin will send a "Modified" booking email to the visitor. You can customize the content of the "Modified" booking email template at WP Booking Calendar > Settings > Emails page.

Sending Payment Request.
When you click on the "Payment request" button, a popup window will appear where you can enter the payment reason.
The entered "Payment Reason" can be included in the payment request email by using the [paymentreason] shortcode at the WP Booking Calendar > Settings > Emails > Payment Request email template page.
After Visitor Receives the Payment Request Email
When a visitor receives the payment request email and clicks on the payment link, they will be redirected to the payment request page. This page will display the cost corresponding directly to the amount specified in the cost field for the respective booking at the Booking Listing page.

7. Summary about Payment Requests.
Upon completion of the payment by the visitor, administrators can review the booking details within the Notes section associated with the specific booking on the Booking Listing page. This section provides a detailed log of various events related to the booking, including payment system responses, payment section displays, payment request details, and updates to booking costs. Administrators can utilize this information to ensure accurate tracking and management of bookings.

[2024-04-21 15:04] Automatically calculated deposit cost 150
[2024-04-21 15:04] Automatically calculated cost 500

Please note, this configuration is possible at the Business Medium or higher versions.

Description
If you are need to add the additional costs, like tax or some other additional charges (cleaning,breakfast, excursion...), or just increase the cost depend from the visitor number selection at the selectbox, which is depend from the selection of the selectboxes or checkboxes in the booking form, so then you can make this configuration in the Business Medium or higher versions.

Configuration
1) You can insert into the Booking form, at the Booking > Settings > Fields page some checkbox, like this:

Tax: [checkbox* my_tax ""]

If you are need to have this checkbox hidden and checked by default in this way:

<div style="display:none;">[checkbox my_cleaning default:on ""]</div>

If you are need to have this checkbox as required and checked by default so use it in this way:

Cleaning service: [checkbox* my_cleaning default:on ""]

For the selectbox, its can look like this:

Visitors [select visitors "1" "2" "3" "4"]

Please read more about the booking form fields configuration here

2) Then at the WP Booking Calendar > Prices > Form Options Costs page at the advanced cost management section for the option my_tax or/and visitors, set some additional cost.

For example, for the tax 6% you need to set value 106% there.

Or if you want to add the fixed cost value, you can set this value to this "my_cleaning" option:

my_cleaning = 50

or for the visitors selections you can leave this configuration:

visitors:
1 = 100%
2 = 200%
3 = 300%
4 = 400%

Its possible to use arithmetic expressions, including fields shortcodes and simple mathematics operations at the Booking > Resources > Advanced cost page.

Its useful, when you are having checkbox (or selectbox), and want to apply some additional cost depend from selected option in other selectbox or checkbox in booking form.

1) For example, you are having increase of booking cost depend from visitors selection ( in N times),
and also you need to add 50 USD for a breakfast per each visitor, if some checkbox is selected.
Example of configuration fields in the booking form at the Booking > Settings > Form page:

</p>
<p>Visitors:  [select visitors "1" "2" "3" "4" "5"]</p>
<p>Breakfast (+50 USD):  [checkbox breakfast ""]</p>
<p>

In this case you can configure at the Booking > Resources > Advanced cost page for visitors option:

[visitors]
1 = 100%  of total booking cost
2 = 200%  of total booking cost
3 = 300%  of total booking cost
4 = 400%  of total booking cost
5 = 500%  of total booking cost

( [visitors] * 50 )

2) Shortcodes, its the names of form fields, from the "Content of booking fields data" form in Booking > Settings > Form page.
Each such shortcode will be replaced to digital number relative to selected option or checkbox.

3) In case, if the options in selectboxes or checkboxes does not have numbers (but some strings), please DO NOT use such shortcodes!
For example, if you have shortcode like this in booking form:

[select visitors "1" "2" "3" "4"]

But if you are having shortcode like this at the Booking > Settings > Form page:

[select visitors "Person 1" " Person 2" " Person 3" " Person 4"]

4) Tip. The value of each selected checkbox = 1 and value of not checked checkbox is 0.

5) Please note, you need to use parentheses ( and ) to separate each mathematical operation.

Please use instead of expression like this

5 - 3 * 2

( 5 - ( 3 * 2 ) )

Supporting since update 8.2 in Booking Calendar Business Medium or higher versions.

You can configure the booking form to display only the selected payment method after the booking process. To do this, use the following shortcode in the booking form at WP Booking Calendar > Settings > Booking Form page:

Select payment method: [select payment-method "All payment methods@@" "Stripe@@stripe_v3" "PayPal@@paypal_std_co" "Authorize.Net@@authorizenet" "Opayo - Elavon@@sage" "Bank Transfer@@bank_transfer" "Pay in Cash@@pay_cash" "iPay88@@ipay88" "iDEAL Buckaroo@@ideal"]

You can customize the shortcode to include only the active payment gateways that you've enabled at WP Booking Calendar > Settings > Payment Setup page.

After the visitor selects a specific payment system in the booking form, only that payment form will be displayed after the submission of the booking.

This feature is also useful in Booking Calendar Business Medium or higher versions for setting additional "Payment system fee" (commission) at WP Booking Calendar > Prices > Form Options Costs page. Check more about this feature here. Watch it in this video guide.

Short answer to this question, it does not possible. But you can configure auto cancellation of unpaid bookings, and auto approving of paid bookings during specific times.

Booking is created before payment process in any case. You need to activate the auto approve / cancel bookings at the Booking > Settings > Payment page in Stripe or PayPal section, etc..

Also you can activate auto cancellation of pending bookings that have no successfully paid status after a specific amount of time. You can activate this option at the Booking > Settings General page in the "Auto cancellation / approving" section.

It means that if the booking is not approved, and does not have the successfully paid status, this booking can be auto canceled after a specific amount of time.

Or you can even activate to show the "Pending bookings as available dates" - you can activate this option at the Booking > Settings General page in Advanced section.

---
Important info about payment status and auto-cancellation of bookings.
But you need to be sure that all "good" bookings have to be approved or have successfully paid status.

Because if you are using the PayPal standard integration and your visitors make the payment for the booking, but do not click on the "return link" on PayPal site to your site, so Booking Calendar does not know that the payment is successful, and this booking can be auto canceled with that feature.
Stripe has to auto redirect to booking page automatically.

So sometimes it's possible that the successfully paid bookings will not have this status and that's why it can be auto-canceled, if you do not approve them.

Ideally (for PayPal) you will need to activate and correctly configure the PayPal IPN system, at the Booking > Settings > Payment page and in the PayPal account. So in this case the PayPal has to send the messages directly to your booking system.

---
When auto cancellation starts work ?

The Auto cancellation starts work when someone opens the front end side of your website. Please open the page with your booking form, and then check your booking at the Booking Listing page, relative Auto cancellation.
Also please recheck your timezone configuration at the WordPress > Settings General page. It can be an issue relative to the not right time of auto-cancellation.

So please note, auto-cancellation can execute every 1 hour (or other period), if you have configured CRON at your website or if some visitor has visited your website, and cancellation time exceeds that specific "auto cancellation " time duration from last cancellation .

If nobody visit website during "1 hour" (or other period of time), so system just does not start script for initializing checking about (auto cancellation, etc... ) some bookings. In this case, you need to configure CRON script at your server. Please check more about configuration of CRON.

In pure WordPress system it working with pseudo-cron functionality:

WordPress Cron is what many people refer to as a “pseudo-cron system.” The difference is in how UNIX cron and WordPress Cron take action. A typical UNIX cron system runs in this order:
- A time tied to an action occurs.
- Cron runs the action tied to that time.

With WordPress Cron, it works a little differently:

- A visitor comes to any page on your WordPress website.
- WordPress Cron checks each cron event to see whether the scheduled time has passed.
- If the scheduled time for that event has passed, then WordPress Cron executes any actions tied to that event.

This instruction is explain how to start work with integration your payment gateway into Booking Calendar Business Small or higher versions of update 7.0 or newer, based on exist payment gateway.

Let say that your new payment gateway have name: loc_payment.

1) You need to create new folder, like this:

../{Booking Calendar Folder}/inc/gateways/loc_payment/

../{Booking Calendar Folder}/inc/gateways/loc_payment/wpbc-gw-loc_payment.php

2) After this you can copy/paste code from file

../{Booking Calendar Folder}/inc/gateways/stripe/wpbc-gw-stripe_v3.php

3) Then check your code relative comments in this new file and configure your payment form and settings, relative to API and help info from website of your new payment gateway.

4) Additionally you need to add one new hook for ability to load the new payment gateway

// General API for Adding new gateways:
function add_my_gateway( $gateway ){ return $gateway . ',gateway_ID'; }
add_filter( 'wpbc_gateways_original_id_list', 'add_my_gateway' );

In your case you need to have something like this:

function add_my_loc_payment( $gateway ){ return $gateway . ',loc_payment'; }
add_filter( 'wpbc_gateways_original_id_list', 'add_my_loc_payment' );

5) If your payment gateway have response functionality, then you can check this function:

function wpbc_payment_response__stripe_v3( $parsed_response ) {

Use these shortcodes for customization:

Simple HTML Configuration

Now, you can organize your booking form fields in rows and columns using the new Simple HTML shortcodes. This makes configuring your booking form even easier.

Here's how it works:

Example of how to create a single row with 2 columns:

    <r>
      <c>...</c>
      <c>...</c>
    </r>

With this feature, you have the flexibility to design your booking form exactly as you need it. (Available in all paid versions).

Create Rows. Use these tags to defines a row in your form:

    <span class="tag"><r></span><span class="pln">...</span><span class="tag"></r></span>

Add Columns. Inside each row, you can specify columns using tags:

    <span class="tag"><c></span><span class="pln">...</span><span class="tag"></c></span>

Label Fields. Use the tags:

    <span class="tag"><l></span><span class="pln">...</span><span class="tag"></l></span>

Spacer:

    <span class="tag"><spacer></spacer></span>

or

    <span class="tag"><spacer></span><span class="pln">width:1em;</span><span class="tag"></spacer></span>

Simplified field data tag:

    <span class="tag"><f></span><span class="pln">...</span><span class="tag"></f></span>

Easily highlight field data by enclosing it within tags in the 'Content of booking fields data' section on the Booking > Settings > Form page:

    <span class="tag"><f></span><span class="pln">...</span><span class="tag"></f></span>

This will highlight the background of the field on the Booking Listing page. (All Pro Versions). For example

    <span class="tag"><f></span><span class="pln">[secondname]</f</span>

The ability to have several different custom booking forms with different form fields configurations possible in the Booking Calendar Business Medium or higher versions.
Check more about this feature here. Watch it in this video guide

1) At the front-end side, you can define the showing of a custom booking form or standard form, depending on the form_type parameter in the Booking Calendar shortcode. Please check more here https://wpbookingcalendar.com/faq/shortcode-booking-form/

For example, showing standard booking form:

[booking type=1 nummonths=2 form_type='standard']

Showing some custom booking form:

[booking type=1 nummonths=2 form_type='my-custom-form']

2) For correct showing data at the Booking Listing page and in Calendar Overview pages and emails, depending on specific custom booking form relation to specific booking resources, then you need to define specific custom booking form as Default at the Booking > Resources page for specific booking resources.

3) If you are using the booking resource selection shortcode like in this example, then if you want to show the custom booking form for specific booking resources, you need to define specific custom booking form as default at the Booking > Resources page. You will need to use shortcode like this, without the form_type parameter in shortcode, to load specific custom booking form relative to specific booking resources (check more about configuration here )

[bookingselect label='Please select the resource:' nummonths=1 type='17,16,15']

But if you will use shortcode with form_type parameter in shortcode, then system will load for all booking resources the default booking form or custom booking form depends from your parameter:

[bookingselect label='Please select the resource:' form_type='standard' nummonths=1 type='17,16,15']

   <p>Last Name of 2nd visitor:<br />[text* secondname_2nd] </p>
</div>
<div class="visitors_selection_div v_num3 v_num4" style="display:none;">
   <p>First Name of 3rd visitor:<br />[text* name_3rd] </p>
   <p>Last Name of 3rd visitor:<br />[text* secondname_3rd] </p>
</div>
<div class="visitors_selection_div v_num4" style="display:none;">
   <p>First Name of 4th visitor:<br />[text* name_4th] </p>
   <p>Last Name of 4th visitor:<br />[text* secondname_4th]</p>
</div>
<script type="text/javascript">
   jQuery('.visitors_selection').on('change', function() {
       var visitors_num = jQuery(this).find(":selected").val();
       jQuery('.visitors_selection_div').hide();
       jQuery('.visitors_selection_div.v_num' + visitors_num ).show();
   });
</script>

Description of this code:
We are having 3 additional DIV elemtns, where exist fields shortcodes for entering First and Last names of visitors. All these DIV elements does not visible for the visitors

style="display:none;"

We attach JavaScript function for selection of the visitors number:

jQuery('.visitors_selection').on('change', function() {

var visitors_num = jQuery(this).find(":selected").val();

jQuery('.visitors_selection_div').hide();

jQuery('.visitors_selection_div.v_num' + visitors_num ).show();

For ability to open the booking form in popup window (in paid versions of Booking Calendar), please follow these steps:
1) Create new page (or edit existing page) and add the "Custom HTML block" to the page.
Then insert the code similar to this:

<script src="https://server.com/wp-content/plugins/booking/assets/libs/ui/_out/dropdown_modal.js"></script>
<a  href="javascript:void(0)" onclick="javascript:jQuery('.bookingFormModal').wpbc_my_modal('show');"
    class="wp-element-button">Booking</a>
[booking resource_id=1]

Where [booking type=1] - shortcode for your booking form. Please check more here.

Also you need to define correct URL to dropdown_modal.js script.

<script src="https://server.com/wp-content/plugins/booking/assets/libs/ui/_out/dropdown_modal.js"></script>

2) Now open the WP Booking Calendar > Settings > Booking Form page and configure the booking form similar to this:

<div class="wpdevelop">
    <div class="modal bookingFormModal" tabindex="-1" role="dialog" style="display:none;z-index:9999999;">
        <div class="modal-dialog modal-lg" role="document">
            <div class="modal-content">
              <div class="modal-header"><button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button><h4 class="modal-title">Booking Form</h4></div>
              <div class="modal-body">
<!-- Start Booking form configuration -->				  </p>
<p>[calendar]
<div class="standard-form">
     <p>First Name (required):<br />[text* name] </p>
     <p>Last Name (required):<br />[text* secondname] </p>
     <p>Email (required):<br />[email* email] </p>

     <p>Children:<br />[select children "0" "1" "2" "3"]</p>
     <p>Details:<br /> [textarea details] </p>
     <p>[checkbox* term_and_condition use_label_element "I Accept term and conditions"] </p>
     <p>[captcha]</p>
     <p>[submit class:btn "Send"]</p>
</div></p>
<p> <!-- End configuration  of the booking form -->
             </div>
            </div>
        </div>
    </div>
</div>
<style type="text/css"> .wpdevelop .modal { overflow-y: scroll; } </style>

3) The result will be like this:

Such configuration possible in the Booking Calendar updates 9.8 or newer.

Customization for Booking Calendar Version 9.8.9 or Newer Updates

Single Day Selection
Activate the Single Day Selection mode with the following code. This code is used to enable single-day selection in the current booking form if you have a different type of day selection set as the default at the General Booking Settings page.

[booking resource_id=1]
<script type="text/javascript">
   var wpbc_resource_id = 1;
   wpbc_cal_ready_days_select__single( wpbc_resource_id );
</script>

Please note that in this code, the line var wpbc_resource_id = 1; defines the ID of the booking resource (calendar). You can find the IDs of your booking resources on the Booking > Resources page. Be sure to use the same resource ID in the shortcode with the wpbc_resource_id parameter.

Multiple Days Selection
Enable Multiple Days Selection mode with the following code:

[booking resource_id=1]
<script type="text/javascript">
   var wpbc_resource_id = 1;
   wpbc_cal_ready_days_select__multiple( wpbc_resource_id );
</script>

Please note that in this code, the line var wpbc_resource_id = 1; defines the ID of the booking resource (calendar). You can find the IDs of your booking resources on the Booking > Resources page. Be sure to use the same resource ID in the shortcode with the resource_id parameter.

Range Days Selection with a Fixed Number of Days with 1 Mouse Click.
Activate the Range Days Selection with a fixed number of days using a single mouse click with the following code:

[booking resource_id=1]
<script type="text/javascript">
   var wpbc_resource_id = 1;
   wpbc_cal_ready_days_select__fixed( wpbc_resource_id, 7, [-1] );
</script>

Parameter #1 - Resource ID:
The line var wpbc_resource_id = 1; define the ID of the booking resource (calendar). Locate the IDs of your booking resources on the Booking > Resources page, and ensure you use the same resource ID in the shortcode with the wpbc_resource_id parameter in JavaScript code.

Parameter #2 - Number of Dates to Select:
The second parameter, in our case, sets the number of dates for selection to 7 days.

Parameter #3 - Start Week Day(s) Selection:
The third parameter, represented as an array, allows you to specify the starting day(s) of the week. Assign values according to the following:

    0: Sunday
    1: Monday
    2: Tuesday
    3: Wednesday
    4: Thursday
    5: Friday
    6: Saturday

For example, if you want the start day of the range selection to be Saturday and you want to select 2 days, use this code:

var wpbc_resource_id = 1;
wpbc_cal_ready_days_select__fixed( wpbc_resource_id, 2, [6] );

If you want to set the start day of range selections as Monday and Friday and make a selection of 4 days, use this code:

var wpbc_resource_id = 1;
wpbc_cal_ready_days_select__fixed( wpbc_resource_id, 4, [1,5] );

The following codes are equivalent:

var wpbc_resource_id = 1;
wpbc_cal_ready_days_select__fixed( wpbc_resource_id, 7, [-1] );

var wpbc_resource_id = 1;
wpbc_cal_ready_days_select__fixed( wpbc_resource_id, 7, [0,1,2,3,4,5,6] );

Range Days Selection as a Dynamic Range of Days with 2 Mouse Clicks.
This code enables this type of day selection for the current booking form if you have a different type of day selection set as the default at the General Booking Settings page.
Activate the Range Days Selection with a dynamic range of days using 2 mouse clicks with the following code:

[booking resource_id=1]
<script type="text/javascript">
  var wpbc_resource_id = 1;
  wpbc_cal_ready_days_select__range( wpbc_resource_id, 7, 14, [], [-1] );
</script>

Parameter #1 - Resource ID:
The line var wpbc_resource_id = 1; define the ID of the booking resource (calendar). Locate the IDs of your booking resources on the Booking > Resources page, and ensure you use the same resource ID in the shortcode with the wpbc_resource_id parameter in JavaScript code.

Parameter #2 - Minimum Number of Days to Select:
The second parameter defines the minimum number of days to select. In our example, it's 7 days.

Parameter #3 - Maximum Number of Days to Select:
The third parameter represents the maximum number of days to be selected with 2 mouse clicks. In our example, it's 14 days.

Parameter #4 - Specific Number of Days to Select:
The fourth parameter is an array that specifies the specific number of days that can be selected.
- To allow any number of days, use this parameter: []
- To allow only week-based selections, such as 7 days, 14 days, 21 days, and so on, use this parameter: [7,14,21].

Parameter #5 - Start Week Day(s) Selection:
The fifth parameter is an array where you can specify the start day of the range days selection.
Specify a specific day of the week or multiple days as the start day for the range selections, use the following values:

    0: Sunday
    1: Monday
    2: Tuesday
    3: Wednesday
    4: Thursday
    5: Friday

For example, to start the range selection on Saturday and make a selection from 3 to 10 days, use this code:

var wpbc_resource_id = 1;
wpbc_cal_ready_days_select__range( wpbc_resource_id, 3, 10, [], [6] );

To start the range selection on Monday and Friday and make a selection of only weeks, use this code:

var wpbc_resource_id = 1;
wpbc_cal_ready_days_select__range( wpbc_resource_id, 7, 28, [7,14,21,28], [1,5] );

The following codes are equivalent:

var wpbc_resource_id = 1;
wpbc_cal_ready_days_select__range( wpbc_resource_id, 7, 14, [], [-1] );

var wpbc_resource_id = 1;
wpbc_cal_ready_days_select__range( wpbc_resource_id, 7, 14, [], [0,1,2,3,4,5,6] );

If you're using version 9.7.7 or older, you can refer to the Legacy FAQ for Configuring Different Types of Day Selection at this link.
This resource should provide the guidance you need for configuring different types of day selection in your older version of the plugin.

You can customize the number of months to scroll using JavaScript, allowing for different settings than the general configuration defined in option "Number of months to scroll" at WP Booking Calendar > Settings General page in the "Calendar" section.

To do this:

1) Add a Custom HTML block to your website near your Booking Calendar block. This block allows you to insert JavaScript code into your page.

2) If, for example, you have a booking resource with ID = 4 and need to set the number of months to scroll as 2 years, you can use the following JavaScript code:

Example #1

<script type="text/javascript">
    var my_resource_id = 4;                                                                      /* Defining ID of booking resource - calendar */
    _wpbc.calendar__set_param_value( my_resource_id,'booking_max_monthes_in_calendar','2y' );    /* Defining number of months to  scroll. Can be Years: '4y' or Months: '6m' */
    wpbc_cal__re_init( my_resource_id );                                                         /* Update look  of calendar */
</script>

To set the number of months to scroll as 5 months for the booking resource with ID = 1 (which is the default booking resource in the Booking Free version), you can use the following code:

Example #2

<script type="text/javascript">
    var my_resource_id = 1;                                                                      /* Defining ID of booking resource - calendar */
    _wpbc.calendar__set_param_value( my_resource_id,'booking_max_monthes_in_calendar','5m' );    /* Defining number of months to  scroll. Can be Years: '4y' or Months: '6m' */
    wpbc_cal__re_init( my_resource_id );                                                         /* Update look  of calendar */
</script>

These scripts allow you to customize the scrolling behavior for specific booking resources on your website.

In Booking Calendar Business Large or higher versions possible to define capacity for booking resources (calendars), for ability to receive several bookings for the same date(s)/times in the same calendar (booking resource).

Please read more about it here.
Configuration. Set capacity of booking resources at WP Booking Calendar > Resources page. You can read more info about configurations of booking resources, capacity and availability at this page.
You can test it in the live demo.

Its means that during the booking process, user can book several "child booking resources" and deduct availability for selected date on number of booked "child booking resources". This number (how many items to book), can depend only from one field, that you defined at the WP Booking Calendar > Settings General page in "Capacity" section as the option for "Quantity field name", after enabling this toggle: "Booking Quantity Control".

Usually it is field from the booking form (configured at WP Booking Calendar > Settings > Booking Form page), such as this:

Visitors: [select visitors class:visitors "1" "2" "3" "4" "5" "6"]

It is often require to make deduction of availability based on 2 parameters - selection of "adults" and "children" number.
In this case possible to make this JavaScript customization in the booking form, for automatic selection of specific number of visitors, depend from the selection of number of "adults" and "children" in booking form.
Example of configuration:

<r>
        <c> <l>Adults:</l><br />[select adults class:adults "1" "2" "3"]</c>
    <c> <l>Children:</l><br />[select children class:children "0" "1" "2" "3"]</c>
</r>
<r>
    <c>
        <l>Total number of visitors:</l><div class="visitors_num">1</div>
        <div class="total_visitors_count">[select visitors class:visitors "1" "2" "3" "4" "5" "6"]</div>
    </c>
    <style type="text/css">
        .total_visitors_count select { visibility:hidden;}
     </style>
<script type="text/javascript">
    jQuery( 'select.adults').on( 'change',  wpbc_set_visitors_number );
    jQuery( 'select.children').on( 'change',  wpbc_set_visitors_number );
function wpbc_set_visitors_number() {
    var s_adults   = jQuery('select.adults option:selected').val();
    var s_children = jQuery('select.children option:selected').val();
    var s_visitors = parseInt(s_adults) + parseInt(s_children);
console.log( s_visitors );
jQuery('select.visitors option[value=' + s_visitors + ']').prop({selected: true});
    var resource_id = jQuery( "input[name^='bk_type']" ).val();
    jQuery('.visitors_num').html(s_visitors);
    if (typeof(showCostHintInsideBkForm) == 'function') {
          showCostHintInsideBkForm( resource_id );
    }
}
</script>
</r>

In case, if you select adults and children than available slots for the booking, system does not allow to submit the booking and show warning.

1) Firstly, create a new post or page, and insert into content of the page this shortcode:

[bookingedit]

2) Now, open the general booking settings page and at the "Manage bookings section" for field: "URL to edit bookings" write (paste) the URL to the page from point #1. Save the changes of this settings page.

In old versions of Booking Calendar this field located at the Booking > Settings General page in "Advanced" section:

3) Open Booking > Settings > Emails page and inside of email template(s), where it's possible (you can check it at help section under the each email template), you can use these shortcodes (for the inserting links into the email templates), which are sending to the visitors:

[visitorbookingediturl]

[visitorbookingcancelurl]

[visitorbookingpayurl]

4) You can test it for a new bookings.

Configuration of ability to view and manage all previous bookings of user, at front-end side of your website. Visitors of your website, can view previous (own) bookings, by clicking on secret link in email, which is sending after booking created.

Important! Please note, if you open this page directly, you will see this warning "You do not set any parameters for booking editing". It's because system allow to open this page only from link(s) in email templates, which your website visitor had to received, after he/she made the booking (inside of that link will be specific parameter (secret HASH) for the identification of the booking). Check more about such type of configuration here.

Such shortcodes possible to use in the Booking > Settings > Emails page in New (admin) email template only.
Available since update 8.5.1 of paid versions of Booking Calendar.

Using of such shortcodes require correct configuration of [bookingedit] shortcode in your system.
Please check this FAQ instruction how to configure it.

You can enable the "Redirect to thank you page" option on the Booking > Settings General page in the "Booking Confirmation" section. This allows visitors to be redirected to a specified page after creating a new booking. To showcase the confirmation and "booking details" on this page, simply insert the following shortcode:

[booking_confirm]

For guidance on inserting Booking Calendar shortcodes into a page, refer to the instructions on this page, particularly in the 4. Manual Shortcode Configuration section.

To enable the display of the booking admin panel exclusively for specific users, you'll need to install an additional plugin that restricts access to other pages in the WordPress admin panel. You can use the "User Role Editor" plugin or any other plugin of your choice that offers similar functionality.

Follow these steps to show only the booking admin panel for "Subscriber" users in your WordPress admin panel:

• Navigate to WP Booking Calendar > Settings General page in the "Plugin Menu / Permissions" section. Set the value "Subscriber" for each plugin menu option in the "User permissions for plugin menu pages" section.
• Install the "User Role Editor" plugin by going to WordPress > Plugins > "Add New Plugin" menu. Alternatively, install another plugin that can restrict access to the WordPress admin plugin pages.
• Open the Users > User Role Editor page and ensure that only one "Read" capability is defined for "Subscriber" users. Save changes.
• Log in with another WordPress user who has only the "Subscriber" user role and test it.

Important Note: If you have any questions about configuring the "User Role Editor" plugin or another plugin with similar functionality, please contact the support of that specific plugin for assistance. We can only provide help with configuring the Booking Calendar plugin. Thank you for your understanding.

This feature is available only at Booking Calendar Business Medium or higher versions.
You need to create new custom booking form at the Booking > Settings > Form page, and define several calendars.
Example, of configuration booking form with several calendars of different booking resources:

<style type="text/css">
	.flex_container { display: flex; flex-flow: row wrap; justify-content: space-around; }
	.flex_item { flex: 1 0 auto; }
</style>
<div class="flex_container">
	<div class="flex_item">[calendar]</div>
	<div class="flex_item">[calendar id=2]</div>
	<div class="flex_item">[calendar id=3]</div>
</div>
<div class="standard-form">
     <div class="form-hints">
          Dates:[selected_short_timedates_hint]  ([nights_number_hint] - night(s))<br><br>
          Full cost of the booking: [cost_hint] <br>
     </div><hr/>
     <p>First Name (required):<br />[text* name] </p>
     <p>Last Name (required):<br />[text* secondname] </p>
     <p>Email (required):<br />[email* email] </p>
     <p>Adults:  [select visitors "1" "2" "3" "4"]</p>
     <p>[submit class:btn "Send"]</p>
</div>

Where [calendar] - default calendar. You define this booking resource in the Booking Calendar shortcode, during inserting it into a post or page, for example in shortcode like this (inside of the content of the page) [booking type=5 ]. This shortcode define the main calendar (booking resource) with ID = 5 (parameter type=5 ).

[calendar id=2] - calendar of booking resource with ID=2

[calendar id=3] - calendar of booking resource with ID=3

etc...

Its does not possible to select several time-slots (possible to select only one), if you are using Booking Calendar Free version of in paid versions using range-time shortcode:

Select time-slot: [select rangetime "10:00 - 12:00" "12:00- 14:00" "14:00 - 16:00" "16:00 - 18:00" "18:00 - 20:00"]

Instead of time-slots selection you can use start time and end time selections or start time and time duration selections shortcodes at the Booking > Settings > Form page in paid versions of Booking Calendar. So you can book several consecutive hours during specific day.

1) Star time and duration of time shortcodes, for ability to book several consecutive hours during a day:

Start time: [select starttime "10:00" "11:00" "12:00" "13:00" "14:00" "15:00" "16:00" "18:00"]
Time Duration: [select durationtime "15min@@00:15" "30 min@@00:30" "45 min@@00:45" "1 hour@@01:00" "1 hour 30 min@@01:30"]

2) Or you can use start time and end time selections or time entering shortcodes:

 Start time: [select starttime "10:00" "11:00" "12:00" "13:00" "14:00" "15:00" "16:00" "18:00"]
 End time: [select endtime "11:00" "12:00" "13:00" "14:00" "15:00" "16:00" "19:00"]

You can configure the time-slots selections on the Booking > Settings > Form page. Please use the "shortcode generator" on the right side of that page for the correct generation of the shortcode.
Please watch more in this video: https://wpbookingcalendar.com/help/booking-calendar-video-timeslots/

  Default: [select rangetime "14:00 - 16:00" "16:00 - 18:00" "18:00 - 20:00"]
[/condition]
[condition name="season-times" type="season" value="High_season"]
  High season: [select rangetime  "10:00 - 12:00" "12:00 - 14:00" "14:00 - 16:00" "16:00 - 18:00" "18:00 - 20:00"]
[/condition]
[condition name="season-times" type="season" value="Low_season"]
  Low season: [select rangetime "12:00 - 14:00" "14:00 - 16:00"]
[/condition]

Additional info.
Please note, if you will activate the "Multiple days" selection or "Range days" selection in the General Booking Settings page at calendar section, so all these conditions will be based on the "first" day of that selection in the calendar.

You need to define the times selection in booking form at the Booking > Settings > Form page in a way like this:

<p class="times_section">Select Start times:<br />[select starttime class:start_selection "All day(s) booking@@00:00" "08:00" "08:30" "09:00" "09:30" "10:00" "10:30" "11:00" "11:30" "12:00" "12:30" "13:00" "13:30" "14:00" "14:30" "15:00" "15:30" "16:00" "16:30" "17:00" "17:30" "18:00" "18:30" "19:00" "19:30" "20:00" "20:30" "21:00"]</p>
<p class="times_section time_duration_section">Select time duration:<br />[select durationtime class:duration_selection "All day booking@@24:00" "1 hour@@01:00" "2 hours@@02:00" "3 hours@@03:00" "4 hours@@04:00" "5 hours@@05:00" "6 hours@@06:00" "7 hours@@07:00" "8 hours@@08:00" "9 hours@@09:00" "10 hours@@10:00"]</p>

2) Also you need to add custom JavaScript code, that will show the "duration of time", only in case, if you will select other value than "All day booking", and hide the times fields from the booking form, at all, if you select more than 1 day:

<script type="text/javascript">
    jQuery('.start_selection').on('change', function() {
       var start_time = jQuery(this).find(":selected").val();
	   if ( '00:00' == start_time ) {
       	  jQuery('.time_duration_section').hide();
		  jQuery('.duration_selection').val( '24:00' );
		  jQuery('.time_duration_section option:first').css('display', 'block');
	   } else {
          jQuery('.time_duration_section').show();
          jQuery('.duration_selection').val( '01:00' );
		  jQuery('.time_duration_section option:first').css('display', 'none');
	   }
     });
     jQuery(document).ready(function(){
		jQuery('.start_selection').val( '00:00' );
		jQuery('.duration_selection').val( '24:00' );
		jQuery('.time_duration_section').hide();
     });
     jQuery( ".booking_form_div" ).on('date_selected', function(event, bk_type, date) {
                   if ( ! jQuery( this ).is( ':visible' ) ) {
                      return false;
                   }
                   var dates_count =  date.split(',');
		   dates_count = dates_count.length;
		   if ( dates_count > 1 ) {
		       jQuery('.start_selection').val( '00:00' );
		       jQuery('.duration_selection').val( '24:00' );
		       jQuery('.times_section').hide();
		   } else {
		       jQuery('.start_selection').val( '00:00' );
		       jQuery('.duration_selection').val( '24:00' );
		       jQuery('.times_section').show();
			   jQuery('.time_duration_section').hide();
		   }
		 if (typeof(showCostHintInsideBkForm) == 'function') {
               showCostHintInsideBkForm( bk_type );
         }
     });
</script>

So full minimum booking form configuration can look like this:

[calendar]
<div class="form-hints">
          Dates:[selected_short_timedates_hint]  ([nights_number_hint] - night(s))<br><br>
          Full cost of the booking: [cost_hint] <br>
</div><hr/>
<div class="times-form">
	<p class="times_section">Select Start times:<br />[select starttime class:start_selection "All day(s) booking@@00:00" "08:00" "08:30" "09:00" "09:30" "10:00" "10:30" "11:00" "11:30" "12:00" "12:30" "13:00" "13:30" "14:00" "14:30" "15:00" "15:30" "16:00" "16:30" "17:00" "17:30" "18:00" "18:30" "19:00" "19:30" "20:00" "20:30" "21:00"]</p>
	<p class="times_section time_duration_section">Select time duration:<br />[select durationtime class:duration_selection "All day booking@@24:00" "1 hour@@01:00" "2 hours@@02:00" "3 hours@@03:00" "4 hours@@04:00" "5 hours@@05:00" "6 hours@@06:00" "7 hours@@07:00" "8 hours@@08:00" "9 hours@@09:00" "10 hours@@10:00"]</p>

       	  jQuery('.time_duration_section').hide();
		  jQuery('.duration_selection').val( '24:00' );
		  jQuery('.time_duration_section option:first').css('display', 'block');
	   } else {
          jQuery('.time_duration_section').show();
          jQuery('.duration_selection').val( '01:00' );
		  jQuery('.time_duration_section option:first').css('display', 'none');
	   }
     });
     jQuery(document).ready(function(){
		jQuery('.start_selection').val( '00:00' );
		jQuery('.duration_selection').val( '24:00' );
		jQuery('.time_duration_section').hide();
     });
     jQuery( ".booking_form_div" ).on('date_selected', function(event, bk_type, date) {
                   if ( ! jQuery( this ).is( ':visible' ) ) {
                      return false;
                   }
                   var dates_count =  date.split(',');
		   dates_count = dates_count.length;
		   if ( dates_count > 1 ) {

		 if (typeof(showCostHintInsideBkForm) == 'function') {
               showCostHintInsideBkForm( bk_type );
         }
     });

It's possible at the Booking Calendar Business Small and Business Medium versions of Booking Calendar in update 4.1 or newer.

You can activate "Use check in/out time:" option at the General Booking Settings page.
Then in the sub-settings set the "Check in" time as 15:00 and "Check out" time as 10:00. (You can set the different times there, but be sure to set the "Check In" time older than "Check Out").
Save the settings page.

Now, your visitors will be able to use the same date as check in/out date for the different bookings, its mean if the some booking is finished on the specific date, other visitor can start the new booking on the same specific date.
The check in/out days in calendar will be marked as half booked (diagonal line) and not by clock icon as for the usual timeslots.

Please note, this option will apply globally to the all booking resources and will overwrite any time slots, if you will use them in the booking form.

If you are need to use just time slots in the booking form, so you are need to deactivate this option and configure the time slot selection at the Booking > Settings > Fields page. Please read more about the booking form fields configuration here.

If you're using the changeover days functionality, which allows half-day bookings, but you need specific booking resources to have time slots or full-day bookings, you can exempt certain pages from the changeover days functionality.

1. Navigate to WP Booking Calendar > Settings General page in the "Calendar" section.
2. Activate the option "Use changeover days" (this option is only available if you've enabled "Multiple" or "Range" days selection modes).
3. Enable the option "Do not use changeover days on certain pages".
4. Enter the relative URLs of the pages for which you do not want to use the changeover days functionality. Enter one URL per line. For example: "/page-no-change-over/".

This functionality is available in update 10.1 of Booking Calendar Business Large and Booking Calendar MultiUser versions.

This feature allows you to easily customize search availability for booking resources. Personalize search visibility and attributes by customizing options like summary text and thumbnail images to enhance user engagement in search results. Additionally, configure specific parameters for resource filtering in search forms, providing users with targeted and relevant search options.

Search for Specific Time Slots
Now you can search for specific time slots on particular dates or even a range of dates. This is a fantastic feature for appointment-based businesses, allowing clients to find available time slots for different service providers. Imagine searching for an available hair stylist, doctor, or other service provider on a specific date and time. You can even set an approximate date range (+/- N days from the desired date) to find appointments within a specific time slot.

1) Requirements. This functionality available in the Booking Calendar update 8.0 or newer version.
So if you are using some older paid version of Booking Calendar, then you can request the new update of Booking Calendar on this page: https://wpbookingcalendar.com/request-update/

2) Requirements. Additionally for ability to import bookings from external websites, like Airbnb, Booking.com, HomeAway, TripAdvisor, VRBO, FlipKey and any other calendar that uses .ics format, you will be need to install Booking Manager plugin update 2.0 or newer ( https://wordpress.org/plugins/booking-manager/ ).

3) Getting URL of .ics feed. Now, when you have installed both plugins, you can start configuring of import events/bookings from external website.

First of all you need to get URL of .ics feed, from where you want to import the events/bookings.
Let make example based on Google Calendar. At other websites, you need to check help documentation where exactly you can find URL of .ics feeds: Airbnb, Booking.com, HomeAway, TripAdvisor, VRBO, FlipKey

3.1) Open Google Calendar then mouse over specific calendar and click on settings icon at right side near specific calendar, then click on "Settings and Sharing" link.

3.2) Scroll to "Integrate calendar" section, and copy URL of "Secret address in iCal format"

4) Inserting Booking Manager import shortcode(s). You will be need to insert the Booking Manager Shortcode for importing of events into some post or page.
The easiest way todo this is clicking on "Booking Manager" button in edit content toolbar:

Then in popup dialog switch to the "Import .ics feed into WPBC" tab.
Paste URL to your .ics feed in specific feed, and configure other parameters, like booking resource (in paid versions), where you want to import bookings, start and end date of import and other parameters.

Please read more about manual configuration of Booking Manager import shortcode at this page.

5) Publish such page(s)

Please note, now, when someone will visit this page, the import process from this specific .ics feed will start into the booking resource, which you have specified in booking manager shortcode.

When you will visit such page, so then you will see how many bookings was imported:

6) CRON. Its means that you need to visit such page periodically for start importing of bookings that can be created at other website. The best way its to configure CRON at your server for periodic access such page(s) and import of bookings from different sources. Please read more about CRON .
Probably you will be need to contact your server administrator or support of hosting, if you will have some difficulties with configuring CRON at your server.

Repeat steps 3 - 6 for different .ics feeds from different sources and for different booking resources (in paid versions of Booking Calendar).

7) TIP. As you can see from Booking Manager Shortcode, you can define in shortcode different URL to .ics feed and specific booking resource (in paid version). Using such shortcodes in different pages give a great flexibility to import from different .ics feeds (sources) into the same resource. Like one page for import from Airbnb and other page with different shortcode for importing from booking.com or Google Calendar. Also you can define different time interval in your CRON for accessing different pages and its means to start import of bookings with different intensity.

1) Requirements. This functionality available in the Booking Calendar update 8.0 or newer version.
So if you are using some older paid version of Booking Calendar, then you can request the new update of Booking Calendar on this page: https://wpbookingcalendar.com/request-update/

2) Requirements. Additionally for ability to export bookings into external websites, like Airbnb, Booking.com, HomeAway, TripAdvisor, VRBO, FlipKey and any other calendar that uses .ics format, you will be need to install Booking Manager plugin update 2.0 or newer ( https://wordpress.org/plugins/booking-manager/ ).

3) Export URLs. Now, when you have installed both plugins, you can start configuring of export bookings into external website.

Please open the Booking > Settings > Sync > Export -ics page.

Configure URLs for each booking resources (in paid versions). In the Booking Calendar Free version, you will see field for configuring URL for your one Default booking resource. Then click on Save changes button.

4) Import .ics in external website. Now you need to check documentation of each other external website, of how to start import of .ics feeds into specific services: Airbnb, Booking.com, HomeAway, TripAdvisor, VRBO, FlipKey

Important! Please note, once you have imported specific .ics feed into external website or application, its does not mean that this operation will be executed periodically. You need to check documentation of specific service (like AirBNB), for ability to import such .ics feeds periodically for having your bookings in external website always up to date.

Example of how to import .ics files in Google Calendar.

If you get error during generating .ics feed or getting just empty space instead of .ics feed.

In case, if you start import of .ics feed into Google Calendar by URL "Other Calendars > Add by URL", then in the point #3 you need to configure URL that ending with wpbm.ics. For example:

/ics/apartment2/wpbm.ics

1) So please try to configure link with wpbm.ics at the end of links at the Booking > Settings > Sync > "Export - .ics" page, like this:

/apartment2ics/wpbm.ics

After this click on icon near specific .ics feed url (check in point #3 in first screenshot point #3), its will open new .ics feed in new browser window. And you have to see .ics feed. Basically in browser window you have to copy full URL and then use it in other services.

2) If you still have an issue. Please recheck your error.log in your server configuration, about any relative errors.
If you can not find error.log file, please contact support of your hosting company about helping in finding this file.
Just to recheck about the reason of this issue. May be you have not activated some PHP module.

3) Be sure that you are using latest versions of Booking Calendar and Booking Manager.

What fields are exported from Booking Calendar to .ics feed?

Booking Calendar export bookings via .ics feeds by assigning these booking form fields to the fields in .ics feed:

SUMMARY

In the Booking Calendar Free version assign to 'SUMMARY' field in .ics feed, one of exist fields from your booking form, that can have names like this 'name', 'firstname', 'secondname', 'lastname'

In the paid versions of Booking Calendar possible to define, what exactly field from the booking form to assign to 'SUMMARY' field in the .ics feed. You can define it at the Booking > Settings General page in "Admin panel" section in the option "Booking title (admin panel)"

DESCRIPTION

Booking Calendar export all bookings details (that you have defined as fields at the Booking > Settings > Form page) to this field 'DESCRIPTION' in the .ics feed.
Please note, in the paid versions, all such bookings details defined at the "Content of booking fields data" form at the Booking > Settings > Form page.

Please note, the import process is working in that case, when some visitor is open your website page with booking import shortcode.
For start import of .ics feeds in "automatic" way you need to configure the CRON script at the server, for periodically accessing the page with booking import shortcode.

You need to define the CRON command to access the page with your import .ics feeds shortcodes, during each 1 hour (or other reasonable period of time). So CRON script will access the page with import .ics feeds shortcodes in your website, and during these times, will be start of import process, from your other services.

Example of CRON command (for every 1 hour to run):

0 * * * * wget -qO- https://your-server.com/your-page-with-import &> /dev/null

Instead of "your-server.com" use your website DNS. In other words the URL like this https://your-server.com/your-page-with-import , it's URL to the page at your website, where you have inserted into the content of this page the import .ics feed shortcode. Check more about import .ics feeds shortcodes.

Each .ics feed can contain info about the event in following fields:
- Event Title
- Event Description (optional field)
- Location
and dates of event, of course.

1) During import of .ics feed from external source into the Booking Calendar, you can assign each such specific field to one of exist fields in the booking form. You can make this assignment at the Booking > Settings > Sync > "General" page in "Import > Assign events fields to specific booking form field" section.

Please note, email field here is not required (but this field is required for the Booking Calendar). So that's why during import of events from .ics feed into the Booking Calendar created new email field and assigned your "Administrator email" from your WordPress website.

2) During export of events from the Booking Calendar into the .ics feed, Booking Calendar assign following values to standard .ics feeds fields: "Title" and "Description".

If you are using the Booking Calendar Free version, so then plugin export into "Title" field following fields (if fields with such names exist in your configuration at Booking > Settings > Form page): 'name' 'firstname' 'secondname' 'lastname'.

In paid versions of Booking Calendar, plugin export into "Title" field of specific event, - configured "Title" of booking that is showing in Calendar Overview (timeline) page in booking pipelines. This configuration you can find at the Booking > Settings General page in "Booking Admin Panel" section, in option "Booking title (admin panel)" - default title of bookings in calendar view mode at Booking Listing page.

As "Description" field, Booking Calendar export all booking data of specific booking. In paid versions of Booking Calendar its configuration of "Content of booking fields data" form from Booking > Settings > Form page.

If you need to remove any booking data (in "Title" and "Description" fields) in your exporting .ics feed, then you can activate this option "Remove booking details in exported .ics feed" at the Booking Manager plugin at menu "oPlugins Panel" > General Settings page. In this case, system will export only booked dates into the .ics feed without any additional details. this option available in Booking Manager update 2.0.12 or newer.

P.S. In case, if you need to make some your customization of such import / export process, so then you can find needed info for import in this file: ../wp-content/plugins/booking-manager/core/wpbc/wpbm-bc-import.php

function function wpbm_ics_import_start( $attr )

and for export in this file: ../wp-content/plugins/booking-manager/core/wpbc/wpbm-bc-export.php

function wpbm_export_ics_feed__wpbm_ics( $param = array( 'wh_booking_type' => '1', 'wh_trash' => '' ) ) { 

P.S.S. Disclaimer. Unfortunately we can not start, right now, some personal customization or custom development, because almost have no free time. Check more about new features here https://wpbookingcalendar.com/faq/need-new-feature/
Please note, if you will modify the source code of the Booking Calendar, we will not guaranteed the correct work of plugin and do not support it.

Typically, exporting from Booking Calendar to Google Calendar isn't directly supported. However, there's a workaround:

• Open the settings for your specific Google Calendar.
• Select "Add calendar" and then choose "From URL."
• Define the URL to the .ics feed from Booking Calendar.
  You can find this URL on the page: WP Booking Calendar > Settings > Sync > "Export - .ics" page.

Please note: Google Calendar imports events from such .ics feeds only twice per day.

Since update 4.2 of the Booking Calendar the calendar structure CSS file is located at the ../booking/css/calendar.css (please do not edit it or edit it very carefully). The calendar color skins are located in the ../booking/css/skins folder. Inside of these files (for better compatibility), please modify only following parameters:
* background , background-color, background-repeat, background-image, background-repeat, background-position
* border
* box-shadow, -moz-box-shadow, -webkit-box-shadow
* border-radius, -moz-border-radius, -webkit-border-radius
* color
* font-weight
* text-shadow
* text-transform

If you want to add new style.
Go to the folder “BOOKING_PLUGIN_PATH/css/skins/” and add new CSS file (the template you can get from this directory) to this directory. After this select this file at the general booking settings page and save settings.
If you want to customize exist skin.
Go to the folder “BOOKING_PLUGIN_PATH/css/skins/” open your file from this directory and customize it. After customization you need to select this style at the general booking settings page and save settings.

Important! Please note, if you will make upgrade of plugin to the new update, all plugin files is overwriting. Its means that your custom calendar skin also will be overwriting. That's why please backup your custom calendar skin before update and then restore it after update process.

Since new update 5.4 you do not need to backup/restore your custom calendar skins anymore. Just put your custom calendar skin to the special folder. Please save your own custom calendar skin to the /wp-content/uploads/wpbc_skins/ folder. You need to create this folder /wpbc_skins/ inside of your /wp-content/uploads/ folder, because this folder has not created automatically. Its will save your custom calendar skin, if you will make upgrade of plugin to new plugin update.

You can check this instruction how to edit CSS file from WordPress menu.

By default the "partially booked dates" (its means bookings for specific time-slot and available in Booking Calendar Business Medium or higher versions) is showing with small calendar icon at the bottom right side in each specific day cell, where exist bookings for specific time-slot. Because such bookings for time-slots can have pending or approved status, system also change background color for such dates.
Such workflow can be confused for some customers and sometimes need to show only calendar icon, but leave background color for such dates the same as for available dates. For having such view, you will be need to make some small fix in your calendar skin.

1) First of all, please check what calendar skin is active in your system. You can check it at the Booking > Settings General page in Calendar section. Please note, you calendar skin can be located at ../{Booking Calendar Folder}/css/skins/ or at ../{Booking Calendar Folder}/inc/skins/

2) Because you will be need to make fix, probably you need to create your own calendar skin in specific separate folder ( /wp-content/uploads/wpbc_skins/ ), its will save your customization during future updates of plugin. Please check how todo this here.

3) You will be need to add to the bottom of your calendar skin the CSS code for redefinition background color and text folor for such days.
For example for the "Premium Marine" calendar skin, this color can look like this:

.block_hints .block_time,
.datepick-inline .timespartly {
    background-color: #789;
}
.datepick-inline .timespartly.date_available a{
    color:#fff;
    font-weight: 600;
    text-shadow: 0 -1px 0 #333;
}

/* A V A I L A B L E - BACKGROUND */

/* A V A I L A B L E  - Text A */

After saving your calendar, skin (if you was creating your own calendar skin), please open the Booking > Settings General page and select for "Calendar Skin" your new calendar skin file. Then save changes.

Please do not forget to clear browser cache before testing these changes.

This feature possible to configure, only in the Booking Calendar Business Large or higher versions. Because only in these versions possible to set capacity per calendar, and to have different availability per days depend from number of bookings. Please check more about this here: https://wpbookingcalendar.com/overview/#capacity

1) Firstly please check this instruction how possible to configure your calendar skin by modification CSS file: https://wpbookingcalendar.com/faq/change-skin-and-colors/

2) Then you need to activate this Calendar Skin: "Multidays" at the Booking Settings General page in Calendar section.

This calendar skin have special CSS classes for ability to define different colors in calendar depend from capacity of booking resource (calendar) and number of bookings per specific date(s) (in other words based on availability on specific date). Probably you will be need to copy this calendar skin to separate folder, as explained in above instruction for future customization.

3) Each calendar day cells (in this calendar skin) have specific CSS classes like:

.reserved_days_count1
.reserved_days_count2
.reserved_days_count3
...
.reserved_days_count8
.reserved_days_count9
.reserved_days_count10
...
The number at the end of this class is explain the availability per specific days.

So in case (if you have capacity per booking resource as 10) you can configure in your calendar skin these colors for the different color for the different availability:
You can just add this code to the bottom of that calendar skin.

/* Partially availability: 1-7 */
.datepick-inline .reserved_days_count1,
.datepick-inline .reserved_days_count2,
.datepick-inline .reserved_days_count3,
.datepick-inline .reserved_days_count4,
.datepick-inline .reserved_days_count5,
.datepick-inline .reserved_days_count6,
.datepick-inline .reserved_days_count7{
    background-color: #eb5;
     color: #eeeeee;
     text-shadow: 0px -1px 0px #888888;
}
/* Availability 8-10 */
.datepick-inline .reserved_days_count8,
.datepick-inline .reserved_days_count9,
.datepick-inline .reserved_days_count10 {
    background-color: #1A5;
     color: #eeeeee;
     text-shadow: 0px -1px 0px #888888;
}
/* Approved */
.block_hints .date_approved.block_check_in_out,
.block_hints .block_booked,
.datepick-inline .date_approved,
td.timespartly.check_in_time.check_out_time.check_in_time_date2approve.check_out_time_date_approved div.check-in-div,
td.timespartly.check_in_time.check_out_time.check_out_time_date2approve.check_in_time_date_approved div.check-out-div {
    background-color: #ee5933;
}
/* Pending */
.block_hints .date2approve.block_check_in_out,

  background-color: #ee5933;
}

You can define showing calendar months in several rows in "option" parameter of Booking Calendar shortcode, during inserting this shortcode into your page or post. Please read more about this configuration here.

This customization is only for the Booking Calendar Free version. In the paid versions, you can easily configure booking form fields and their style at the advanced form configuration at the Booking > Settings > Fields page.

Customization.
1) Please open this file ../wp-content/plugins/{Booking Calendar Folder}/css/client.css
and add to the bottom of that file this code:

.booking_form .control-label {
  color: #FFF;
}

Of course instead of white color #FFF you can set some other.

2) In the same way possible to change the color of text inside of the text fields, text-area elements and selectboxes. You need to add to the bottom of this file ../wp-content/plugins/{Booking Calendar Folder}/css/client.css this code:

.booking_form_div select,
.booking_form_div textarea,
.booking_form_div input[type="text"] {
  color: #FFF;
}

Again instead of white color #FFF you can set some other color.

Important! Please note after update of plugin to the newer version update, you will be need to make this fix again, because all Booking Calendar files will be overwritten.

How to edit plugin file in WordPress 4.9 or newer

Paid versions of Booking Calendar support configuration in different languages of the booking form, email templates and some other text options in the settings . The active language of the booking form depends on the active locale of the site.

Booking Calendar supports WPML and Polylang plugins for dynamic changing of website locale (language).

General Usage:
[lang=LOCALE] - start a new translation section in a specific language, where LOCALE - locale of the translation.

Example of English and French translation of "Thank you" message:

Thank you for your booking.[lang=fr_FR]Je vous remercie de votre réservation.

Important!
Please note, English language is the default language in the Booking Calendar plugin. You need to start with English section (without [lang=...] shortcode at the top of form), and then continue with all other language sections divided by shortcode [lang=LOCALE],  where LOCALE its locale of specific language,  like de_DE,  or es_ES,  etc...

Of course you can have more than 2 language sections.

Example of configuration booking form in English and French languages at the Booking > Settings > Fields page:

[calendar]
First Name (required): [text* name]
Last Name (required): [text* secondname]
Email (required): [email* email]
Visitors: [select visitors "1" "2" "3" "4"]
Details: [textarea details]
[submit "Send"]
[lang=fr_FR]
[calendar]
Prénom (obligatoire): [text* name]
Deuxième prénom (requis) [text* secondname]
Email (obligatoire) [email* email]
Visiteurs : [select visitors "1" "2" "3" "4"]
Détails : [textarea details]
[submit "Envoyer"]

In the same way, you can configure the email templates on the Booking > Settings > Emails page and search form on the Booking > Settings > Search page, etc..

For example, the German translation file may be named as booking-de_DE.po, and the Spanish translation file may be named as booking-es_ES.po. Find the full list of locales in WordPress on this page.
2. Placeholder Variables: Be attentive to placeholders for variables such as %s, %d, %f, etc. Ensure that you maintain the placeholders in the same position as in the original translation line. The number of placeholders must be consistent with the original translations. For more detailed information about placeholders for variables in translations, check here.
3. Using Poedit:
   • Start the Poedit program.
   • Click on "Browse Files" or select File > Open from the menu, or press Ctrl + O.

     • The filename of the plugin (in this case, "booking").
     • The Locale (for example, for Spanish translation: "es_ES"). So, the name would be "booking-es_ES.po". Find the full list of locales in WordPress on this page.
   • Save the file to the "languages" folder of the plugin.
3. Translation Process:
   • Begin the translation.
   • Placeholder Variables: Be attentive to placeholders for variables such as %s, %d, %f, etc. Ensure that you maintain the placeholders in the same position as in the original translation line.

On the Booking Listing page exist ability to change language (locale) of emails, that will send to visitor during approving or declining of the booking. But how to detect language/locale of webpage, from where visitor submit the booking.
Here is instruction how to do this.
Please open the Booking > Settings > Fields page and add to the booking form this shortcode and JavaScript code:

<div style="display:none;"> Active Language: [text active_language class:wpbc_lang_field]</div>
<script type="text/javascript">
 jQuery(document).ready(function(){
    jQuery('.wpbc_lang_field').val( wpbc_active_locale );
 });
</script>

Its will add to your booking form new field [active_language] and JavaScript for auto-inserting active locale into this field. Please note, this field is not visible for visitors, because of this CSS: style="display:none;"

Also you will be need to add to the "Content of booking fields data" form (its at the bottom of Booking > Settings > Fields page) this shortcode:

<strong>Active Language</strong>:<span class="fieldvalue">[active_language]</span>

For showing this field at the Booking Listing page.

There are 2 types of Booking Calendar translations.

1) One list of translations located at WordPress repository. Please note, these translations at your website should be located at: "../wp-content/languages/plugins/" folder.

2) Another list of translations located at the Booking Calendar website. You can download the original PO translations files from here. Please note, these translations at your website should be located at: "../wp-content/plugins/{Booking Calendar Folder}/languages/" folder.

By default Booking Calendar plugin try to use translations from "../wp-content/languages/plugins/",
if failed (not exist), then try to use translations from "../wp-content/plugins/{Booking Calendar Folder}/languages/" folder.
This behavior is possible to change at the Booking > Settings General page in the Translation section.

You can check instruction how to make or update local plugin translation files at this page.

Translations available in paid versions of Booking Calendar:

1. If something does not seem to be sending correctly, install the WP Mail Logging Plugin to check logs of email sending.
2. Check SPAM / JUNK folder in your mail system.
3. Check that you have activated and configured the email templates at the Booking > Settings > Emails page.
   • For each email template (switch tabs at toolbar) recheck that you have correct email addresses.
   • Option "Enable / Disable" at the specific email template must be checked.
   • Field "From" at the specific email template must to have the same website DNS as your website. 

     Sometimes mail servers block emails, if the address "From" different from the domain of website, from where this email was sending. Please open the Booking > Settings > Emails page and recheck that field "From" have the same email as your website domain. For example: info@your-server.com and not like this your_email@gmail.com, where your-server.com it's your website domain.

   • If you are using paid versions of Booking Calendar, please be sure to configure the email field at the Booking > Settings > Form page, like this [email* email]. Its default primary email field for booking form! Please do not use other names for this email field. For example: Email (required):[email* email]
   • Optional. Try to set for field "To" in the "New (admin)" email template the same email that you was used in field "From" at this email template page.
4. This is most common reason of not receiving emails!

   In most situations you will need to install  and configure some SMTP plugin.
   We can recommend to install and configure the WP Mail SMTP plugin, but you can  search  and install  any other SMTP plugin: https://wordpress.org/plugins/search/smtp/.

   Why you need to have SMTP plugin?
   SMTP plugins have to fix your email deliverability by reconfiguring WordPress to use a proper SMTP provider when sending emails.This is a problem for a lot of WordPress sites because by default, WordPress uses the PHP mail function to send emails generated by WordPress.The issue is that most WordPress hosting companies don’t have their servers properly configured for sending PHP emails. 
   The combination of two causes your WordPress emails to not get delivered.

   It also  can  be a reason why  your emails are marked as spam.
   Please check more here.

   I need help with SMTP plugin configuration.
   Because such plugins was developed by other companies and persons, please contact support of specific SMTP plugin about help in correct configuration of specific SMTP plugin.

5. Please try to test sending of emails by creation of new bookings at front-end side of your website (do not test it from sending test emails at Booking > Settings > Emails page).
6. Check that your PHP mail function is working correctly. You can open your login page and try to retry the password, then check if you received email.
7. If the issue still will exist , please try reconfigure Subject and Content of the email template. Make it simpler. May be because of some server restrictions, you are having blocking of sending these emails.
8. Otherwise you can try to use some other SMTP plugins:

   WP Mail SMTP (plugin support: https://wordpress.org/support/plugin/wp-mail-smtp/ )
   Post SMTP mailer (plugin support: https://wordpress.org/support/plugin/post-smtp/ )
   SMTP Mail (plugin support: https://wordpress.org/support/plugin/smtp-mail/ )

9. Finally, please recheck your error.log and mail.log in your server configuration, about any relative errors.
   If you having troubles with checking these files, please contact support of your hosting company about this.

And you are have JavaScript error, similar to this:

Uncaught TypeError: jQuery(...).wpbc_timeselector is not a function

Error: jQuery("#calendar_booking" + bk_type).datepick is not a function

TypeError: jQuery(...).datepick is not a function

Reason
Reason of this issue is loading of jQuery library 2 times in your website.

The loading process is following:
1) Firstly is loaded the standard jQuery (ver 3.6) from WordPress (and its fine):

<script type='text/javascript' src='../wp-includes/js/jquery/jquery.js?ver=3.6.0' id='jquery-core-js'></script>

<script type="text/javascript" src="..../wp-content/themes/my_custom_theme/js/jquery.min.js"></script>

Please open the header.php (or footer.php) or functions.php file of your theme and comment the loading of the jQuery, to prevent load it for the second time.
Otherwise please contact support of your theme (or plugin) relative loading of jQuery library  in correct  way,  relative to  WordPress best  practice and not load it directly in the header or footer files.

You can have this issue because of having some JavaScript error(s) at your website.
Probably some other plugin or actual theme generate JavaScript error. That's why the calendar do not show.

To recheck your page for JavaScript errors, open the browser console (usually to see JavaScript error(s) press Ctrl + Shift + J, check more here ).

You can also try to check about some conflict with some active plugin or actual theme.
Deactivate one by one all your active plugins at the WordPress > Plugins menu and test about the issue during each deactivation.
If its not help, please deactivate your active theme and active the default WordPress theme.

If you see only calendar at the page, so then probably you have inserted the shortcode for only "availability calendar"

[bookingcalendar type=1 nummonths=2]

instead of shortcode for booking form

[booking type=1 nummonths=2]

Please open the page with booking form for editing, then remove exist shortcode. After this switch from the "Visual" view mode to "Text" view mode your content editor. And then reinsert the Booking Calendar shortcode and test it.
You need to insert this shortcode:

[booking]

Please note, this shortcode [bookingcalendar type=1 nummonths=2] is only for showing availability calendar, without form, where you can not select the dates.

Please read more how easily insert booking form or availability calendar into a pages or how manually configure Booking Calendar shortcodes in content of your pages.

Probably, you have inserted the shortcode for only "availability calendar" [bookingcalendar type=1] instead of shortcode for booking form [booking type=1].

Please note, this shortcode [bookingcalendar type=1] is only for showing availability calendar without form, where you can not select the dates. Booking form shortcode [booking type=1] already contain calendar and there you can select dates and submit the booking.

How to fix it?

Please open that page for editing and then remove exist shortcode.
After this switch from the "Visual" view mode to "Text" view mode your content editor. And then reinsert the Booking Calendar shortcode. You need to insert shortcode like this:

This issue is relative of showing the several booking calendars (booking forms) of the same booking resource at the same "visible" page. Its possible to show only one calendar (booking form) of the specific booking resource at one visible page. You will have no problems to show the calendars (booking forms) of the different booking resources at the same page.

At the Booking Calendar Free version is available only one default booking resource, so its mean that any calendars (booking forms) in this version is belong to the same booking resource. And thats why its not possible to show several booking calendars (booking forms) at the same visible page.

This info is relative to the several booking calendars (booking forms) inside of the content of the page or inside of the content of page and visible booking calendar widget (in this case you are need to deactivate the booking calendar widget, or add the exception of showing the widget at this page).

If you're encountering any of the following issues on your website:

• Booked dates or times are not promptly appearing on the front-end calendar, or there's a significant delay in displaying them after creating new bookings. However, in the admin panel at Booking > Add booking, all bookings are visible as expected.
• When you submit a booking or load the calendar, you encounter an error message: 'Error! Request did not pass a security check! Please refresh the page and try again.'

These problems could be caused by caching on your website.

Here's how to resolve these issues:

1. Update Your Booking Calendar to version 10.1.3 or newer
   Ensure you have updated your Booking Calendar to version 10.1.3 or newer. This update addresses cache plugin issues.
   Important! After updating, clear all minimized CSS and JavaScript files and cached pages or posts.

2. For Booking Calendar Versions 10.1.2 or Older
   1. Check for caching plugins like "WP Super Cache," "WP Fastest Cache," or "W3 Total Cache." If you're using any of these, consider deactivating them or adding an exception for the page with the booking form to prevent caching.
   2. If the problem persists, it might be a conflict with another plugin or your current theme. Deactivate your active plugins one by one in the WordPress > Plugins menu and test after each deactivation. If the issue remains, deactivate all plugins and switch to the default WordPress theme for testing.
   3. If the problem still isn't resolved, contact your hosting support and ask them to check for server-side caching. Request that they add exceptions for the pages with booking forms to prevent caching or inquire about deactivating the caching system.

   This error usually occurs when the NONCE field in the booking form is outdated. The NONCE field is a hidden field with a unique value that prevents remote (CSRF/XSRF) attacks. It is a standard security practice for all WordPress forms.

   The primary cause of this issue is caching.

   Steps to Resolve in versions 10.1 or older and in some cases in new updates:

   1. Check for Cache Issues:
      • This error often stems from caching problems on your server, cache plugins, or caching tools/software.
      • Check for any cache plugins like "WP Super Cache", "W3 Total Cache", "WP Optimize", "WP Rocket", etc... If you use any, deactivate them or add an exception to the page with the booking form to prevent it from being cached.
   2. Deactivate Plugins:
      • If the issue persists, deactivate your active plugins one by one from the WordPress > Plugins menu and test the booking form after each deactivation.
      • If this does not resolve the issue, deactivate all plugins and activate the default WordPress theme. Then, retest the booking form.
   3. Check Server Caching:
      • If none of the above steps work, there may be caching at the server level.
      • Contact your hosting provider’s support team to check for any server-side caching tools or software.

By following these steps, you should be able to resolve the security check error and ensure your booking form works correctly.

   1. Open the WP Booking Calendar > Settings General page in the "Advanced" section and ensure that the option "Load JS and CSS files only on specific pages" is not activated. It must be disabled.
   2. Check for any cache plugins such as "Jetpack Boost", "WP Super Cache", "WP Fastest Cache", "W3 Total Cache", or other cache plugins. If you are using any of these plugins, please deactivate the cache plugins or add exceptions to the page(s) with a booking form to prevent caching of these pages.

      If you are using the Jetpack Boost plugin, please follow this troubleshooting instruction.
      If you are using another cache plugin, contact the support of your cache plugin for instructions on how to add exceptions to the pages with booking forms to avoid caching these pages and prevent concatenation of JavaScript files by the Booking Calendar.

   3. If the issue persists, it may be due to a conflict with another plugin or your current theme.

   This issue arises when the Concatenate JS feature in Jetpack Boost is enabled. To resolve this, you'll need to exclude specific JavaScript files from being concatenated in the Jetpack Boost settings.

   Here are the JavaScript handles you need to exclude:

   wpbc-global-vars, wpbc-popper, wpbc-tipcy, wpbc-datepick, wpbc_all, wpbc-main-client, wpbc_capacity, wpbc-times, wpbc-time-selector, wpbc-timeline-flex

   To do this, simply copy this list and paste it into the "Exclude JS Strings" field within the Concatenate JS module. You can access this module by navigating to Jetpack -> Boost in your WordPress dashboard.

   By excluding these scripts from concatenation, you can ensure that the Booking Calendar functions correctly on your site while still benefiting from other features of Jetpack Boost.

   For additional info please contact the support of your cache plugin for instructions on how to add exceptions to the pages with booking forms to avoid caching these pages and prevent concatenation of JavaScript files by the Booking Calendar.

1) Firstly please open the Booking > Settings > Emails page and deactivate all email templates.
Then try to make new booking. If you will be able to make new booking, so then its means following:

Some severs can block sending emails and generate "500 Internal Error", when you send it to visitor from domain different from your website. You need to check, if this condition set in your server configuration.

• Please try to set in the field "From" instead of visitor email shortcode, your email (its at the Booking > Settings > Emails page). The same email that you set in the field "To".
• Sometimes mail servers block emails, if the address "From" different from the domain of website, from where this email was sending. Its not really depend from the Booking Calendar. So please open the Booking > Settings > Emails page and recheck that field "From", its have to the same as your website domain. For example: info@your-server.com and not like this your_email@gmail.com

Otherwise, please contact support of your hosting company about recheck conditions, when your server block sending of emails.

2) Such error can be because in your server configuration (probably at the WordPress > Settings > General page for the options "WordPress Address (URL)" or "Site Address (URL)") configured different Domain that you try to submit the booking

For example, in Ajax URL its can be set as "https://www.yourserver.com/wp-admin/admin-ajax.php"
and you try to submit the booking from https://www.yourserver.com/education/bookings/

Because booking is sending from HTTP to HTTPS, we are having such type of error.

Please recheck your server configuration at the Settings General page as in above description, or in some other place, where you are set using HTTPS instead of HTTP protocol.

You need to use the same protocol in both ways. If you will have difficulty with searching where exactly you are having this issue, please contact your server administrator who make that configuration.

The same issue can be if you configured sever address with "www." But trying to submit booking from URL without "www." prefix in URL. Or backward.

3) Also please try to deactivate one by one all your active plugins at the WordPress > Plugins menu. Then retest it again.
If its not help, please deactivate your active theme and active the default WordPress theme. And then retest it again. May be there exist some conflict with some active plugin or actual theme and just need to find the reason of that issue.

4) If the previous solutions will not help, please recheck your error.log file from your server configuration (please contact your server administrator or support of the hosting company, if you will have troubles with searching of this file) to be sure in a reason of that issue.

If during export bookings to .ics feed at the WP Booking Calendar > Settings > Sync > "Export - .ics" page you have 404 error, then check these steps:

2. Recheck that you have correctly configured .ics feeds URLs for exporting. Open WP Booking Calendar > Settings > Sync > "Export - .ics" page and be sure that you have specified URL for exporting .ics feeds with one level of depth. For example: https://server.com/ics/my_resource/ or if its not work try to set it as this URL: https://server.com/ics/my_resource/wpbm.ics
3. Please double-check the root folder of your website for any .htaccess files. Make sure these files don't have security restrictions affecting link generation. It's a good idea to reach out to your hosting support for assistance, as they are more knowledgeable about potential security restrictions.
4. Take a look at any other security plugins in the WordPress > Plugins menu that might be blocking the creation of the URL structure for the .ics feed. Try deactivating each active plugin one by one and test after each deactivation. If the issue persists, deactivate all plugins and switch to the default WordPress theme. Test again to see if this resolves the problem.
5. Review your server's error.log for any related errors in your server configuration. If you can't locate the error.log file, contact your hosting company's support for assistance in finding this file.
6. If the previous steps don't resolve the issue, it suggests there might be server configuration restrictions. In this case, only your hosting support or server administrator would know how to reconfigure your server to avoid blocking the generation of the .ics feed. Please inform your hosting support that the "wpbm.ics" file is not a physical file on your server; the script generates it on-the-fly when someone attempts to access the URL defined in WP Booking Calendar > Settings > Sync > "Export - .ics" page.

   Please note, Booking Calendar generate virtual ics feed form the php script. So it’s not the real file at that folder. It’s generate such feed dynamically, when someone access such url.

   System have to work in the same way as WordPress working with pages at your website. As you may know, you can have link to some page like this: https://server.com/category/some-page/ . But it does not mean that you have real file like category/some-page/index.html at your server. Your system access general index.php file at root of your website and then load specific page based on permalink structure. The same with .ics feeds in Booking Calendar, when server try to access url: https://server.com/ics/wpbm.ics
   this .ics feed generate dynamically from the php file.

If you do not see imported bookings, from external .ics feed, then please recheck these points:

1) Please be sure that in your ".ics" feed exist some events, relative to current or future days.
You can download this .ics feed and open in notepad and check your events there.

2) If events was imported before, then such events will not be imported again.
Booking Calendar can import the events from external sources only once (if have not been activated options "Force import" or "Trash all imported bookings before new import" at the Booking > Settings > Sync > "General" page in Advanced section).

May be you are having these event(s) in the Trash or such event(s) was imported into not exist booking resource.

In this case, you need to delete such previously imported bookings (that was imported into non exist booking resource), and then try to import these bookings once again by using correct shortcode.

3) How to check if events, was imported before into Booking Calendar?
3.1) Please update the Booking Manager plugin to the latest update.
3.2) This point work only in Booking Manager 2.0.11 or newer versions.
Open the "oPlugins Panel" > Settings > "Listing Template", and define in listing template these shortcodes:

<p>UID: [UID] ( Booking ID: <a href="[BOOKING_LINK]" target="_blank">[BOOKING_ID]</a>  )</p>

3.3) Open "oPlugins Panel" > "Manage .ics" page, then paste URL of your .ics feed (that you need to check), and click on "Show Events (.ics)" button.
You will see all the events from this .ics feed. Also in each event you will see ID of booking, if its was imported, like this:

Booking ID: 101

Booking ID:

4) If the booking was not imported, then please recheck parameters of import shortcode.
Please check carefully parameters, like:
import_conditions - if you defined import_conditions='if_dates_free', then event will be imported only, if the source booking resource (calendar), have all dates for this event as available
from - date from which start to import events. Usual value: from='today'
until - date of stop import events. Usual value: until='any'

5) Check this instruction how to start import of new events/bookings.

1) Probably you are using the old version of Booking Calendar (9.7.7 or older) and updated to the new WordPress version (6.4 or newer). Because of that you have this issue, where exist conflicts of old version of plugin with new WordPress versions.
Please check more here

2) In order to resolve this issue, please update your version of Booking Calendar to the latest update 9.8.3 or newer update.
You can request the new update of Booking Calendar on this page.

This warning relative to the Booking Calendar MultiUser version.
You can see this warning, because your WordPress user was not activated as regular user in Booking Calendar (have not own booking admin panel) at Booking > Settings > Users page, and this user is not the super booking admin user.

By default the first user in your website, its Super booking admin user.

1) Please login to admin panel with this "first user".
It can be that currently you have logged in with administrator user, that have ID as 5 (or any other). But your WordPress website, also have other administrator users with ID, like 1 or 2. If true, so then you need to login with User with login ID = 1

After this you will see access to the booking admin panel. Then you can activate the booking admin panel for other WordPress users at the Booking > Settings > Users page.

2) In case, if your current user do not have access to the Booking > Settings > Users page, and you do not know login details of your first user, so you can make small customization for activating your actual user as super booking admin user.

You can make this fix.

Firstly please recheck ID of your user. You can open the WordPress > Users page, and then near specific user you can click on edit button, then in browser URL you will see parameter user_id
which will show Id of your user, let say that this ID of your current user is 3

So then, please make this fix.

Please open this file ../{Booking Calendar Folder}/inc/_mu/multiuser.php

( you can check how to edit files in WordPress menu in this article https://wpbookingcalendar.com/faq/how-edit-file-in-wp-menu/ )

then find this code:

$this->super_admin_id = array( $admin_id );                             // ID of Super Administrators

$this->super_admin_id = array( $admin_id , 3 );           // ID of Super Administrators

Firstly you need to check access to the wpdev-booking.php file. If booking plugin is installed to the https://www.myserver.com/wp-content/booking/wpdev-booking.php so copy that link to your browser and check access. Its have to show this error: Fatal error: Call to undefined function get_option(). If you see something like:Error 500 Internal Server Error, so then you need to set access to the wpdev-booking.php file. In most case you just need to set atribute to that file as 755 using your FTP client, sometimes is needed editing .htaccess file. So contact your administrator or check .htaccess file by yourself.

Sometimes wp-content and/or wp-content/plugins and/or wp-content/plugins/booking directories and/or file wp-content/plugins/booking/wpdev-booking.php had permissions set to 777. So its also can make this issue. Please change permissions on those directories and file to 755 and it have to work.

This issue is relative to the configuration of the DNS in your website.
Please try to reconfigure it or contact your administrator for fixing this issue.

Description of reason of the issue.
1) This error "0", can be because in your server configuration somewhere (probably in the WordPress > Settings > General page for the options "WordPress Address (URL)" or "Site Address (URL)") configured different Domain that you try to submit the booking.

For example, in Ajax URL its can be set as "https://www.yourserver.com/wp-admin/admin-ajax.php"
and you try to submit the booking from https://www.yourserver.com/bookings/ Or backward.

You can check it is by viewing the HTML code of your loaded page, in the section:

<!-- Booking Calendar Scripts -->

Because booking is sending from HTTP to HTTPS, we are having such type of error.

Please recheck your server configuration at the WordPress > Settings > General page as in above description, or in some other place, where you are set using HTTPS instead of HTTP protocol.

You need to use the same protocol in both ways. If you will have difficulty with searching where exactly you are having this issue, please contact your server administrator who make that configuration.

The same issue can be if you configured sever address with "www." But trying to submit booking from URL without "www." prefix in URL. Or backward.

2) Also please try to deactivate one by one all your active plugins at the WordPress > Plugins menu. Then retest it again.
If its not help, please deactivate your active theme and active the default WordPress theme. And then retest it again. May be there exist some conflict with some active plugin or actual theme and just need to find the reason of that issue.

If the previous solutions will not help, please recheck your error.log file from your server configuration (please contact your server administrator or support of the hosting company, if you will have troubles with searching of this file) to be sure in a reason of that issue.

Please note, this workflow based on new update 7.0
If you using older version, please update it. For paid versions, you can request the new update of Booking Calendar on this page.

1) Reason of issue.

Such issue possible, if you previously have deleted some booking resources at Booking > Resources page.
And such deleted booking resources was having some bookings. So now you are having in Database such lost bookings.

2) How to fix it.

• Open the Booking Listing page and click on "Reset search filter and user options to default values" button (1)
• Click on "Remove all booking resources" button in toolbar (2)
• You will see all lost bookings (3)
• Click on "Change resource" button and assign to this booking some exist booking resource.

Legacy. How to fix in old versions of Booking Calendar.

Please try to open this link:

https://server.com/wp-admin/admin.php?page=wpbc&wh_booking_datenext=1&wh_booking_dateprior=1&wh_booking_date=3&wh_trash=any&wh_modification_dateprior=1&wh_modification_date=3&wh_pay_status=all&view_mode=vm_listing&wh_booking_type

Since update 7.2.1 please use this link

https://server.com/wp-admin/admin.php?page=wpbc&wh_booking_datenext=1&wh_booking_dateprior=1&wh_booking_date=3&wh_trash=any&wh_modification_dateprior=1&wh_modification_date=3&wh_pay_status=all&view_mode=vm_listing&wh_booking_type=-999

Just replace "server.com" to your website DNS in this URL.

The trick in this link having empty "&wh_booking_type" parameter. Its will show all pending bookings, even if such bookings belonging to the booking resources that have been deleted.

Now, when you will see all such bookings, you will see near some bookings label that "Resource does not exist"
So you can assign to such booking(s) new exist booking resource, by clicking on specific "assign booking resource" button near this booking,
or if you do not need such booking, then please delete completely (even from trash) such booking.

1) This issue can happens in Booking Calendar Business Small or higher versions, if this you have activated using "Check in/out times" (check more about this feature here) at the Booking > Settings General page and incorrectly configured "Check in/out times fields" (usually these fields are empty during this issue.
How to fix.

- You need to be sure that the check in time is older than check out time. For example: Check in: "14:00" and check out: "12:00"
- Or you can simply deactivate "Check in/out times" option, if you do not need to use change-over days.

2) Also this issue possible if you have incorrectly configured time(s) fields at the Booking > Settings > Form page.
You can try to remove any times fields from the Booking > Settings > Form page, or try to reset booking form to one default "Form templates" (you can select one predefined form template at the toolbar, and then click on "Both" button, its will reset your form. After this you can click on "Save changes" button to save these changes.
Otherwise, please use shortcode generator at the right side of the Booking > Settings > Fields page for the fast and correct creation of booking form fields.

3) Other workaround. We do not recommend todo this point, because dropping indexes (as in bellow instruction), will significant impact to speed of loading.
So for fixing this issue, please open the phpMyAdmin or similar tool for the working with DB
and execute this SQL command:

ALTER TABLE bookingdates DROP INDEX booking_id_dates

ALTER TABLE wp_bookingdates DROP INDEX booking_id_dates

This error is appear because of wrong installation of plugin.
1) Please, open the General Booking Settings page and set this option "Delete booking data during uninstall", as unchecked, at the right side of page, otherwise your exist booking data will be delete during deactivation of plugin.
2) Then open the Plugins menu and press Deactivate link of Booking Calendar. Wait, for the message about: "plugin is deactivated successfully".
3) Then press activate link. Wait, until message will show up that plugin is activated successfully.
Now, you can test it again.

1) Go to the general booking settings page and check ON use CAPTCHA check box and save a page.
2) If you use Standard (free) version skip this step, otherwise go to the form fields customization page add captcha shortcode to the customization form:

<p>[captcha]</p>

4) Check that your server was configured for using 2.0 GD library.
Reason.
The cause is that you do not have the version 2.0 GD library loaded in PHP which defines this function, which is used for the captcha in this plugin.

Checking
Use this PHP code to view what extensions you have loaded on your hosting account.

print_r(get_loaded_extensions());
print_r(var_dump(gd_info()));

Just create a text file with the these lines above in your public_html folder (or wherever your web root is), name it with a .php extension like "test.php" and then run it by using your web browser like "https://www.yourdomain.com/test.php "

This does not write correct HTML but will show you the info you need. (Just do a View/Source on your browser if you want a nicer looking format.) Look for text like "[some number] => gd". If you don't see this, you do NOT have the GD library loaded.
Next you want to look for the version number. Something like: ["GD Version"]=> string(27) "bundled (2.0.28 compatible)"
This needs to say version 2.0 or later.

If you do not see GD version 2.0, you must get your hosting provider to install or upgrade your system.

LEARN MORE:
Learn more about the GD library:
https://www.php.net/manual/en/ref.image.php

Learn more about this function:
https://www.php.net/manual/en/function.imagecreatetruecolor.php

5) If you are using Cache plugin (like "WP Super Cache" ), please deactivate it or add the exception to the page with booking form to do not cache this page.

4) Finally, please try to deactivate one by one all your active plugins at the WordPress > Plugins menu. Then retest it again.
If its not help, please deactivate your active theme and active the default WordPress theme. And then retest it again. May be there exist some conflict with some active plugin or actual theme and just need to find the reason of that issue.

If you are still will have this issue, please recheck the error.log in your server configurations to be sure in a reason of that issue.

Kind Regards.

Here is 2 solutions.

A) Upload using FTP manager. It's can be any ftp manager for uploading files to your server. If you do not have FTP access, so then please contact support of your hosting. Also they can recommend to you FTP manager that can be good for your server to upload these files.

1) Please download the archive of the Booking Calendar to your desktop.
2) Extract it from archive. You have to get the "booking" folder.
3) Then upload this folder, using the FTP manager (like FAR or some other) to your server, to the folder

../wp-content/plugins/

4) Now open admin panel of your WordPress site. At Plugins menu, you have to see "Booking Calendar" plugin.
(If you was having previous free version, there, please deactivate it).
Click at the "Activate" link of your new paid version.

5) Please wait until message will show that the plugin is activated successfully. Now you can use the Booking Calendar plugin.

B) Or you can ask your serve administrator or support of hosting company to extend max file-size limit at your server.

Thank you.

This issue can be because of limitation in WAMP configuration.

WAMP can not load large translation php file ( wpbc_all_translations.php ) .

So please open this folder:

..\wp-content\plugins\booking\core\lib

and rename this file:

wpbc_all_translations.php

to this:

wpbc_all_translations2.php

By default Booking Calendar and Booking Manager plugins does not remove or update the bookings, if bookings was changed/canceled at other sources (Booking/Airbnb/Google Calendar).

In the update 8.6 of Booking Calendar or newer and latest update of Booking Manager plugins you can activate this option
"Trash all imported bookings before new import" at the Booking > Settings > Sync page.

Move all previously imported bookings to trash before new import bookings. Its can resolve issue of updating deleted and edited events in external sources. Its work only, if you are using one source (.ics feed) for importing into specific booking resource!

If you notice Booking > Settings General page is not saving, Suhosin (a security module in PHP) may be preventing the POST data from being saved. This issue can also be caused by servers with version PHP 5.3.9+ and servers running mod_security.

If enabled, Suhosin may need to be configured to increase its data submission limits. Changing Suhsoin settings differ from host to host so it’s usually better to consult with the provider than attempt it yourself, however some hosts allow you to change settings via php.ini, suhosin.ini, or .htaccess.
Commonly, the following vars will need changing:

General PHP section

memory_limit = 256M
max_execution_time = 120
post_max_size = 8M
upload_max_filesize = 8M
max_input_vars = 20480
post_max_size = 64M

Suhosin section

suhosin.post.max_array_index_length = 1024
suhosin.post.max_totalname_length = 65535
suhosin.post.max_vars = 2048
suhosin.post.max_value_length = 1000000
suhosin.post.max_name_length = 256
suhosin.post.max_array_depth = 1000
suhosin.request.max_array_index_length = 1024
suhosin.request.max_totalname_length = 65535
suhosin.request.max_vars = 2048
suhosin.request.max_value_length = 1000000
suhosin.request.max_varname_length = 256
suhosin.request.max_array_depth = 1000

After saving you will need to restart the server for the changes to take effect. See https://www.hardened-php.net/suhosin/configuration.html for more information on Suhosin settings.

In shared hosting environments it may not be possible to edit php.ini, in which case you may be able to set the suhosin settings via .htaccess
It is still recommended however to consult your hosting providers documentation, or raise a ticket with them for assistance.

1) Please be sure that you have correctly configured "Content of booking fields data" form at the Booking > Settings > Form page.
For example, if you are having in the booking form configuration like this:

Last Name (required): [text* secondname] 

Last Name: [secondname]

2) Also in some old premium versions of Booking Calendar together with latest update of WordPress possible issue that all entering fields in booking form are blank.
In this case you need to update your version of booking calendar to latest update or rollback your WordPress version.

You can request the new update of Booking Calendar on this page.

After installing update, please make fully NEW bookings to test that booking details is saving correctly.
Kind Regards.

If you are using the booking calendar free version
Try to open the login dialog and retry the password. Then recheck what the email address is used in this email. If you will see the "Wordpress title", so then its somewhere in the settings of WordPress.

Try to open the wp_options table in your DB (using the phpMyAdmin tool or some other DB tool),

Find the option with name "admin_email" and recheck that the email for this field do not have the "WordPress" title.

If you are using the paid version of Booking Calendar, please check this:
Booking Calendar use the standard "WordPress" wp_mail function for sending of the emails, which possibly can be overridden by the other plugins or theme.

Firstly please open the Booking > Settings > Emails page and recheck that you correctly configured the emails in fields "From". that there was no any "WordPress titles". Test it.

Then please try to deactivate one by obe all other active plugins and test if its help or not, may be some other active plugin is override the wp_mail function and thats why you are having that "WordPress" title in the email template. try the same with theme.

For any versions:
Also please open your contact book at youe email account and try to delete that email contact, may be this contact already have the "WordPress" title saved in your contact book at your email account, and thats why you have that "WordPress" title in the emails.

If you try to edit additional cost at the Booking > Resources > Advanced cost page and during saving, all your changes removed back to default values "100%", then please check these steps:

1) Please be sure, if you are using custom booking forms, that the length of custom booking form name not longer than 30 symbols. If its longer, then you need to recreate your custom booking forms.
For doing that, please open the Booking > Settings > Fields page. Select your custom booking form.
Then copy content of "booking form" and "content of booking fields data" form to some TXT file.
Click on "Delete" button in the toolbar to delete this custom form.
Then create new custom form, where name must be not longer than 30 symbols. Paste in the forms your saved data and save changes.
If you was inserting into the posts or pages, booking shortcodes with previous custom form, you need to reinsert them.
Now you can test it.

2) Please be sure that you do not use in the names and values of checkboxes and selectboxes in your booking form some non standard symbols, like umlauts, or % or ' ,etc...
That's why please open the Booking > Settings > Fields page and for the each booking form (if you are having several custom booking forms), please recheck (re-create) shortcodes by using only standard symbols in the names and values.

No, you do not need to make update from WordPress directory, because then you will use Booking Calendar Free version.
We will send to you update(s) of your Booking Calendar version (if these update(s) are ready) by email directly, after you are request update at this page.
