Certain Modules Still Looking For Old Database

:unsure:

Recently, I decided to upgrade my CRM. I initially tested the upgrade on a test database. I then decided to switch the instance over to the database the older version ran on. It works, for the most part. There are still a few bugs.

For this post, there are parts of the system that still tries to look for the old database, despite that fact that I changed databases in the config.php file.

What gives?

Are these custom modules? Could be a caching issues, do a quick repair and rebuild.
