Hello

This exception keeps appearing in the DNN Event Log for our DNN 7.2.2 installation. It appears to be related to the Form and List module, but I'm having trouble debugging. Has anyone seen this before?

System.Exception: Unhandled Error:  ---> System.ArgumentException: An item with the same key has already been added.

Did any of you find a solution for this?

I'm seeing the exact same error in my event log (50+ every day). In my case they are related to two different modules: Active Forum and Active Social. However, I think it's related to the platform as nothing was changed in these modules .

I'm running DNN 7.3.4.
