What’s the role of your “Writer” user? For example, are they a contributor, editor, or some custom role? the user will need to be able to add_post_meta for YOURLS to work.
I use an Editor role myself and shorturls are generated automatically. Please provide as much details about your setup as possible. Also perhaps upgrading to WordPress 4.9 would help.
