Hey, i installed the Google Authenticator plugin and activated it. When I go to log on to the backend of my site I'm prompted for my username, password and Google Authenticator code. After I enter these details I see a "Page cannot be displayed" message. If I navigate to the front page of my site I can see the toolbar at the top of the site as if I'm logged in but I cannot get to the wp-admin page. Has anyone else had this problem? Any ideas on how to get it sorted? I've synced both my phone and my server and the times are identical but still no joy.
