Problems after v4.1 Upgrade

We upgraded this past Wednesday and I was able to use the system fine until this morning. I am getting a multitude of weird displays and messages when trying to edit, from big boxes, to no image or function with the edit pencil, to a 503 error (This application is not currently available) to no access. When I have been able to open edit and go to the code screen, hitting save consistently gets an error message, but each time a different message.
