I am having trouble with Excel import. I have scanned previous forum questions and have not come accross the same issue. When I am importing a Excel File I get a pop up box that states: Server Error: An error has occurred while handling the request I have tried to import the simplest file but I still get the same error. This is my Stack Trace: An error has occurred while handling the request.
