usermgr.php stopped working.

My usermgr.php stopped working recently. When I click it, I get:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, webmaster@all-antm.net and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

It's the only part of my gallery that isn't working - I can access everything else without problems. I've tried re-uploading the usermgr.php via FTP, but it didn't fix anything.

Any help would be appreciated.

the latest version is cpg 1.4.14. Update your gallery. This can solve your issue

I upgraded and I still have this issue.

You haven't upgraded as suggested. I have run update.php for you. Try again. If that fails, review versioncheck. If you're convinced that your upgrade went OK, review your server's error log to find out what is actually wrong when you get the "500 internal server error".
