When using RPX with the "Theme-My-Login" plugin, I get an endless loop of login attempts. I use the my Facebook ID to try and log in. In continuously takes me back to the Log in screen. The RPX part of the plug-in shows my name and info from Facebook, but it will not allow me to access the Dashboard.
When I disable the "Theme-My-Login" plugin I am able to get logged in to the WordPress Dashboard. It also shows my Facebook account under my WordPress User account. However, when I elect to "LOG OUT" it signs me out of my WordPress page, but still shows me signed into the Facebook OpenID part of the Log in. All I have to do is click the Log In button again, and it takes me right back to my WordPress Dashboard. It will not totally sign me out.
