NEVER edit php files with the editor in cpanel! Either use the facility in Zen Cart or download the file to your local computer, make your changes with a good text editor and then upload the changed file back to your site. In order for that to work, you'll have to change the permission and then change it back for security reasons. 755 will probably do the trick.
php files should be edited with a good text editor like Notepad++ or Crimson Editor which are both available free on the net. Filezilla is a good, free FTP client.
