# Fatal Error causing 504

 * Out of nowhere both my sites began experiencing the same issue. Something in 
   the plugin is causing the Document List Configuration table on the settings page
   to blow out with like 500 too many empty rows and this is causing a 504 on all
   mdocs admin pages that render the mdocs-list-table.
 * I have absolutely no idea what caused this or how to fix it…
 * Screenshot of my new and ridiculous settings page:
    ============= [tinyurl.com/px67tbfz](http://tinyurl.com/px67tbfz)
 * Error Details:
    ============= An error of type E_ERROR was caused in line 64 
   of the file /mnt/target04/856824/954681/www.–SiteNameRemoved–.com/web/content/
   wp-content/plugins/memphis-documents-library/plugins/mdocs-col-thumbnail-example.
   php. Error message: Uncaught ImagickException: attempt to perform an operation
   not allowed by the security policy `PDF' @ error/constitute.c/IsCoderAuthorized/
   408 in /mnt/target04/856824/954681/www.--SiteNameRemoved--.com/web/content/wp-
   content/plugins/memphis-documents-library/plugins/mdocs-col-thumbnail-example.
   php:64`
 * Any help would be greatly appreciated!
