So, I've upgraded my forums to 4.2.2. Installed the plugin from the link I received in the email from last week to download the plugin.

Installed it and configured it which went smoothly. Logged out of the Admin, and when I go to log in back in , I get the following errors:

Does anyone know what is causing these errors?
