New GoDaddy issue with database

Permalink
One of my clients just upgraded to the new 4GH grid server with GoDaddy, which means that their database now needs to go onto an updated server. I backed up their current database and populated the new database with that information. When I change the connection script to the new database, I get this error:

Fatal error: Call to a member function GetRow() on a non-object in /home/content/53/2183753/html/updates/concrete5.4.1.1/concrete/models/package.php on line 432


I will say that just before the switch, I uninstalled the AddThis package to help optimize load times. A shame a client has to sacrifice functionality for performance.

Nonetheless, anyone know what the issue is?
