Hi all...

I recently updated my DNN from 7.3 to 7.4

Since the upgrade, each time I attempt to add a page or edit an existing page's properties, I get a "Critical Error. Check Event Viewer" message.

Checking the event viewer gives a Page Load Exception error as follows:

Any help in resolving this issue appreciated
