 * Hi. This is not a theme issue nor a plugin issue – i have verified this.
 * When i attempt to edit any theme php file using the Editor – i get the following
   error:
 * **Fatal error: Call to undefined method WPaaS\Cache::flush() in /home/content/
   n3pnexwpnas01_data03/11/3485711/html/wp-content/mu-plugins/gd-system-plugin/includes/
   admin/class-file-editor.php on line 124**
 * Can someone please help me? This occurs every time i try to edit any php file.
   I do not know what that code even means especially no idea on how to fix it.
