Joomla Invalid Session Error

Problem: Today when attempting to login to the administrator (administration) portion of one of my customers Joomla websites, I received an “Invalid Session” error. Internet Explorer only shows the error in the URL and just redirects you back to the login page: Session


Google Chrome actually shows an “Invalid Session” error on the login page:


Solution: You have a session directory specified in your php.ini file that does not exist: session.save_path = “X:/my/session/directory/” Create the directory and make sure it has the proper permissions to resolve this problem.
