Hello,

After I logged to facebook I am redirected on my forum but I have a blank page.
That's the redirect url after I logged into facebook :
http://myforum.com/auth.aspx?auth=facebook&code=AQDzCaQUVCrGPM3t_NJuTQk8yTLydSqUGquWxRTBEgam8I2o1m6ZxlNBGCmeSSzVLUFHCs2mxLHZKnNktZqO7uyfE-F9pcwT5m7Wb_Y02cEGYp_j6WGBng7USKQMJG7Ge5U6CL4aKFEzOa0bA5TwgE9ztRFoAWYzF2wiSM8HBXMhALIeNNFIBWz3TkuTqXEdxnIUht_OnR3CLhBFJ3L-s-mrPuVgjfd4SKgNlQbXtFBJdJ8Zvyl7mUZpvewzCtHOkYxRCf7XbO0w3nZSjAM8-o6UUTcaGPvkjfs4CcDTPkp4OSHYRn4OYivqT6uRZJbeX1g 

If I refresh the page I have a "Forum Error" message.

Does the auth.aspx file exist in the root folder`?

Yes, and it works great with Google and Twitter authentication.

What error message are you getting, any event log entries?

Here is the log :

Error while trying to login or register the facebook user
System.ArgumentNullException: Value cannot be null.
Parameter name: Email cannot be null.
at YAF.Providers.Utils.ExceptionReporter.ThrowArgumentNull(String providerSection, String tag)
at YAF.Providers.Membership.YafMembershipProvider.GetUserNameByEmail(String email)
at YAF.Core.Services.Auth.Facebook.LoginOrCreateUser(HttpRequest request, String parameters, String& message)
at YAF.Auth.HandleFacebookReturn()

I have the same error with you, but i cannot resolve, anyone help us?

I have the same error . anyone help us ?

Thanks

The problem is when the user hides the email address. Yaf throws an error because the email address is needed for the account.

in the next version there will be a warning message instead of the error screen.

In this case , can the user register with the forum account ?
Thanks

Yes the user can register normal without facebook.
