We've updated our client's site from DNN 9.1.1 to 9.6.0, at http://new.rocktransfer.com/. The Service Centers page has the MapMaker module, v. 1.4.2 installed, was working but it is now throwing an error. It says "A critical error has occured. Please check event viewer for details." I don't see a corresponding entry in the Admin Log.
Is this a version issue that you are aware of and what is our solution?
