We have a huge problem now after upgrading to 2.0 and it is that people can’t unsubscribe. When people click on the unsubscribe link they get this. "Uh oh! I think I broke it. If I do it again, please report me to the system administrator! " 500 Internal Server Error ---

Did you upgrade from the panel or manually? Also do you have backups before installing the new version? ---
