I attempted to update from EE 2.7.3 to 2.8.1 using DevDemon Updater. I received a PHP error and Updater tried to repair itself. When I logged back in to the Control Panel, it immediately activate the “Idle Session Detected” popup and when I try to type in my password, it prompts an alert that says “undefined” It doesn’t allow me to log back in. Any suggestions on how to fix this? Thanks.
