I am getting this message when trying to vew a Visualforce page which asks a controller class to redirect to a page if User Profile is X, and to standard page if not. I did not see any errors on the logs. Can anyone give me a clue of what might be happening? Thanks!!

We have two orgs within our company and they both send Case data to a legacy Application. Are the Case Ids unique across both the Orgs?
