How to allow user to navigate between qustions by adding previos question button

Hi Samiullah223,
there is no back button, but another user asked about one a few years ago. Take a look at this old thread, specifically my response here. Looking at that code, it should still work.

You can test by first backing up the functions.php file in your theme folder, then adding the code to the end of that file (you may need to also clear your server cache if using a caching plugin).

I am reluctant to add a dedicated version of this to the core of HD Quiz simply because doing so has the potential to interfere or break other people’s custom addons for HD Quiz. So I need to be very careful about introducing new features that affect things like this.

But I hope this helps and works for you!
