 * One problem I keep running into… If I’m working on editing a theme or child theme
   in the editor, I have to disable the plugin every time I need to save a change.
 * If the plugin is active, it gives the error “Unable to communicate back with 
   site to check for fatal errors, so the PHP change was reverted. You will need
   to upload your PHP file change by some other means, such as by using SFTP.” any
   time I click “Update File”.
 * So I have to constantly disable the plugin when modifying themes or child themes.
