Uriel,
Sorry for the delay! I just got into the admin area of your site and tested some more. The first thing I did was delete the account I had created the other day and simply looked around at your settings. Everything looked right to me, so I simply tried to click the Login with Facebook button again.
At that point, my full profile was pulled in as it should be. I'm not sure what changed, but it seems to be working. I actually deleted my account 3 different times and re-registered. Each time, my profile was pulled in correctly.
Can you test again? Not sure what happened, but it's difficult to debug something that works

If it doesn't work for you though, just let me know and we can test from other accounts and different ways.
Hopefully, it's all good though!
Alex
