I get an error when trying to start edit mode: "Server Error in '/' Application. Object reference not set to an instance of an object" The same error also occurs in the toolbar in admin mode. Anyone seen this before? Maybe it has something to do with security, I'm not sure that I have been logged in correctly, but how do I log out?! I have tried restarting the computer, deleting cookies and other temporary internet files but no luck. / Anna.
