Issue: User receives 'Sign On Error' when trying to login to Blackboard.
Resolution: Once you see this error, you will need to clear the history, cache, and cookies on your web browser. Below are links for instructions for those steps on Google Chrome and on Firefox (the two recommended browsers for Blackboard SaaS). Again, this is a temporary measure until we have a proper fix. You may need to follow these steps multiple times - clearing the browser history may work for a while, but then the error screen will come back.
