Login with Facebook (social login)?

[konstantinos]

Hello,

We are looking to integrate a social login extension that is also compatible with OPC (i.e. register/login with Facebook from the checkout).

We tried the free SLogin but it fails, after the user is succesfully registered, the checkout will not complete, asking for the 'Bill To' details in a warning pop-up (even though they have been filled in properly).

Any ideas appreciated, thanks
