I've been using Google Chrome for a while now, but I just changed computers to Windows 7, and also updated Concrete5 to the latest version. Well, on Friday I could login and work on the website, but today (Monday 2/6) all I get is a greyed-out website (after log-in) and a message "checking for updates" (see attachment).
Well, when I tried IE9, the login screen seems to allow me to log in, but then it kicks me back to the home page of my website, NOT logged in.
