 * Table does not show up in frontend.
    In the backend there is a spinning wheel
   which goes away only after a refresh. The table did work and suddenly stopped.
   version: 2.1.25

 * Hello again.
 * Did you maybe install some new plugins in the meantime, or have you changed the
   theme? This looks like a conflict, so it could be related to that.
 * Can you try disabling other plugins, one by one, and after each deactivation,
   check the page where the table is supposed to show. Once the issue is gone – 
   you will have found the plugin causing the conflict.
 * Kind regards.
