 * We get an error message when users try to download our directory. It downloads
   a “permission-denied.txt” file. I noticed that there’s an error message at the
   top of our plugin page that says:
 * “Warning: call_user_func_array() expects parameter 1 to be a valid callback, 
   class ‘GFQBMS’ does not have a method ‘display_changelog’ in /home1/sukkatshalom/
   public_html/wp-includes/class-wp-hook.php on line 298”
 * Any thoughts?

 * The error is not coming from wpdm. wpdm doesn’t have any class named `GFQBMS`.“
   permission-denied.txt” shows when user doesn’t have access to that file. Select
   proper user roles or “All Visitors” for access field under package settings.
