When installing, the standard filename.php file in admin/includes is missing the "Administrators" file (under configuration).

For STANDARD/NEW INSTALATIONS:
The included zip file contains the file path. Open "catalog" & ftp the "admin" folder to your root.

CHANGE MANUALLY.

Open YOUR root/admin/includes/filename.php

under:
// define the filenames used in the project

ADD this line as the first entry:

define('FILENAME_ADMINISTRATORS', 'administrators.php');
