Hi,
1 hour ago it was still ok.

But now it shows me the loading screen, then does nothing. Almost nothing. It adds a string in the URL bar like this:
mywebsite.com/index.php?fblogin=1
mywebsite.com/index.php?code=4/p247O-mt0aCCe_-ptvQQiOLPvW4Hv6mFbxotD_Guobg#

I am very sure I didn't install any other extension to my system, but now I can no longer login by facebook or google, nor can I register new user. Very frustrated, Please Help!!!!!!

Best regards
