Problem: Error message was thrown when I clicked on a photo in an album:

Fatal error: Class name must be a valid object or a string in /home/getreferences/public_html/includes/common.inc on line 7885

I tried I updating the Media module to take care of it. I tried updating the Media module to both of the following versions: 7.x-2.0-alpha4 and 7.x-2.x-dev. I got an error message in the Status Report stating that I needed to update the File_Entity module to version 2 in order to work with the latest version of the Media module. I tried to uninstall the old File_Entity version 7.x-1.4 to both of the following versions:
7.x-2.0-beta1
7.x-2.0-alpha4

I could not update the File_Entity module to the either version. I tried everything I know at least 3 times to no avail - it didn't work. When I say it didn't work, I mean that the original file_entity module did/would not change from 7.x-1.4 to 7.x-2.0-beta1 or 7.x-2.0-alpha4. I went in through Filezilla and deleted the File_Entity and Media module folders and uploaded the latest version, then tried to enable it - didn't work. I went thru the Drupal module uninstall process to delete the old versions of the File_Entity and Media modules, then tried to enable it (and I disabled everything that was dependent on the modules) - didn't work. I went through the Media Temple file browser and deleted the File_Entity and Media module folders and loaded in the new ones, then tried to enable it - didn't work.

I also looked at a few forums on the matter. I couldn't find the same problem anywhere, but I found some similar issues. None of the steps the forums provided worked either (i.e. "completely uninstall the media module and the file_entity module and load the latest file_entity module in 1st then load the latest media module..."). I couldn't delete the old version of the file_entity module, let alone enable the new version.

It just makes no sense to me as what could be the matter. Maybe the file entity module is embedded in the core - but I think the forums would talk to this?

I searched the forums and issue queues in the following pages - maybe I missed something:

Please help...thx
