Upgrading from 7.3 to 9.2 - Type "Telerik.Sitefinity.We

Anyone know why I would get the above mentioned exception when running my site for the first time after upgrading to 9.2? 

Notes: 

1. Why did a dry run of the upgrade prior to running it on the production database/files - we didn't get this error
2. The backend seems to be working with no exceptions
3. This exception is restricted to the Home page ONLY

Here is the stack trace:
