 * Hi,
 * So my WP logs are full of Fatal errors that are created by the pro version of
   the plugin when slacking fatal errors.
 * [08-Nov-2019 04:02:16 UTC] PHP Fatal error: Uncaught Error: Call to undefined
   function list_files() in /mnt/storage/prod/www/wp-admin/includes/plugin.php:241
   
   Stack trace: #0 /mnt/storage/prod/www/wp-content/plugins/fatal-error-notify-pro/
   includes/class-public.php(136): get_plugin_files(‘feedwordpress/f…’) #1 /mnt/
   storage/prod/www/wp-content/plugins/fatal-error-notify-pro/includes/class-public.
   php(297): Fatal_Error_Notify_Public->get_admin_url_from_path(‘/wp-content/plu…’)#
   2 /mnt/storage/prod/www/wp-content/plugins/fatal-error-notify-pro/includes/class-
   public.php(246): Fatal_Error_Notify_Public->get_notification_output(Array, ‘slack’)#
   3 [internal function]: Fatal_Error_Notify_Public->shutdown() #4 {main}
 * The missing function is defined in wp-admin/includes/files.php, maybe explicitly
   include it.

 * Hey [@hughiemolloy](https://wordpress.org/support/users/hughiemolloy/) ,
 * That’s odd. I wasn’t able to reproduce it. And there’s even a check for `function_exists('
   list_files' )` before that runs, which should prevent that from happening.
 * Anyway it wouldn’t hurt to include files.php as well. We’ve updated that and 
   just released v1.5.1 of the Pro plugin. Should show up shortly via automatic 
   update.
 * Thanks!
