Hi after reverting to 188.8.131.52, then modifying it so it would not display available updates, everything had worked fine.
Once I saw your 3.1.1 version, I deactivated and deleted the 184.108.40.206 version and installed the 3.1.1 version. Everything worked great yesterday. Thanks for the new version.
Unfortunately, without changing anything in my platform, or your plugin, I now get the spinner when logging in from the front end.
I also found that I can no longer log in via the native WP Admin login.
The front page login is at: http://www.kassius.ca/login-register/
You can try to login using : UID nick and Pwd nick to test.
