# error message starting open foris calc

Asked by Lydia on 2018-12-13

Hey all together,

when I am trying to start Open Foris calc, I immediatley get an error message, "Error 500 - Internal 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 :)

Hey all together,

I completely uninstalled everything and installed it again - now the problem is solved.
