Hey all together, when I am trying to start Open Foris calc, I immediatley get an error message, "Error 500 - Internal Sever Server Error", it specifies that: "request processing failed" and "Cursor returned more than one result". I don't know what to do, since the programme just doesn't work. Does anyone have a hint what to do? Regards :)
