After installing Invenmanager’s Advanced Articles 5.0
on one of dev servers, we received an error when trying to add or edit content to any of the news articles. We were running DotNetNuke (DNN) 5.2.2 for this install and were upgrading from Advanced Articles 4.2.9.

This is the error we received.

Apparently there is a mis-match with the version of a DLL that DNN was using and the one Advanced Articles wanted to use. This is the fix:

If you have trouble finding a newer version of the DLL you should be able to contact Telerik directly. The only spot i found it was a newer install of DNN.
