Fatal error: Call to a member function RecordCount() on a non-object (SOLVED)

[jmcgin51]

Moving a CMSMS 1.3.0 site from a Windows server to a Linux server.  Database has been migrated successfully.  Files from the old server have been backed up and uploaded successfully to the new server.  Install goes smoothly until page 5 of the install wizard, when I get the following error:

Updating hierarchy positions...[done]

Setting up core events...[done]

Installing modules...
Fatal error: Call to a member function RecordCount() on a non-object in /home/site/public_html/install/lib/classes/CMSInstallerPage5.class.php on line 182

What does this indicate?  I've already re-uploaded all of the \lib\classes\ files to ensure that they're not corrupted.

My modules directory is writable as required in the installer.

(And yes, I will be upgrading to 1.3.1 after I get the migration completed.)

EDIT: Well, I had done a forum search before posting, but while waiting for a response, I tried a couple of different searches, and found a resolution.  Looks like the issue has something to do with the prefix used for the db tables.  I still don't understand, but at least it's working now.

Thanks for your help!
