   Finally found the root of the problem.

   My wp-admin is working via HTTPS. When I try to edit or delete questions in

   wp-admin / Settings / DS_FAQ

   I get the 'Ajax Error 5' mentioned above, and the following line being logged to JS console:

   XMLHttpRequest cannot load http://foo.bar/wp-content/plugins/wp-ds-faq/ajax.php. Origin https://foo.bar is not allowed by Access-Control-Allow-Origin.

   This thread on StackOverflow has some details, I won't copy them here, just go and read there if interested.

   The fix is very simple. My modifications of wp-content/plugins/wp-ds-faq/ajax.php are below.

   Before:

   <?php
   require_once(preg_replace('|wp-content.*$|','', __FILE__) . 'wp-config.php');
   
   header('Content-type: text/javascript; charset='.get_settings('blog_charset'), true);
   header('Cache-control: max-age=2600000, must-revalidate', true);
   
   function error(){ die( "alert('Что-то не заработало :(')" ); }
   
   /* ... */

   After:

   <?php
   require_once(preg_replace('|wp-content.*$|','', __FILE__) . 'wp-config.php');
   
   header('Content-type: text/javascript; charset='.get_settings('blog_charset'), true);
   header('Cache-control: max-age=2600000, must-revalidate', true);
   header('Access-Control-Allow-Origin: '.get_site_url());
   header('Access-Control-Allow-Origin: '.str_replace('http://', 'https://', get_site_url()));
   
   function error(){ die( "alert('Что-то не заработало :(')" ); }
   
   /* ... */

   Two header('Access-Control-Allow-Origin') lines added, that's it.

   Enjoy.
