Trying to set up an EPiServer 7 site with MVC. And everything has gone alright until i tried to create a Group in the Admin interface.
After clicking on the "Add"-button I receive:
Server Error in '/' Application. -------------------------------------------------------------------------------- This request has probably been tampered with. Close the browser and try again.
