 The theme editor (Admin menu/Appreance/Editor) will not saved changes made
 on files such as functions.php, style.css etc. after clicking on the
 "Update File" button. Before the update to version 4.9.5 it was working
 fine.
 Now I get the error message: 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.
