Facebook login failing?

This morning when I try to login by clicking the Facebook login button I get the following error message in the popup window that appears:
I checked in my facebook account, and the bikeradar site is still listed as having permissions etc. (I haven't deleted it or done anything at all to the settings in there).
Had to login with just standard user details instead.
Failed - Unauthorized partner. Unauthorized partner

The 'unauthorized partner' message you're seeing is because our Gigya account is no longer active. We'll remove all the social login buttons shortly.
For the time being, you'll only be able to login using your forum username/password, just like the old days.
