Can anyone help me to debug a 400 error from the Facebook login of Social Connect? All other logins are working fine, and the URL to Facebook appears reasonable (though not sure what it should look like) - ie:
https://graph.facebook.com/oauth/authorize?client_id=my app id]&redirect_uri=http%3A%2F%2Fbangkoktravelthailand.com%2Fwp-content%2Fplugins%2Fsocial-connect%2Ffacebook%2Fcallback.php&scope=email
Is it likely to be a compatibility problem with WP 3.1.4? I also tried Janrain Engage and gave up after an hour of looking for a Facebook API key (which they seem to no longer use).
If this module is no good with 3.1.4 (about to go to 3.2), what other social login module would be worth trying? Getting desperate to get this working for my users.
