 * Hello. I tried adding the featured image to my custom post type admin listing,
   and after I did that, and updated the plugin to the latest verison, I am now 
   getting the follow error on my custom post type:
 *     ```
       Warning: Invalid argument supplied for foreach() in /home/content/61/html/wp-admin/includes/class-wp-list-table.php on line 681
   
       Warning: Invalid argument supplied for foreach() in /home/content/61/html/wp-admin/includes/class-wp-list-table.php on line 681

       ```
   
 * I even tried deleting the plugin, and this was still coming up. Any insight on
   how to possibly fix this would be greatly appreciated. I’m at a loss now, and
   can’t figure out how to restore my columns back. 🙁
 * I also bought the premium add-on a while back too.
 * Thanks in advance!

 * I managed to fix it. It was actually the Quick Edit modification I made a year
   ago. I guess it’s finally dated now and not working too well.
 * This is the modification I am talking about:
