Guayo,
If you try to click the login button when you're already logged into Facebook with an admin of your app, you will hopefully get a different error. If not, these are the usual causes of that problem:
* Your App Domain is not set correctly (this should be taken care of by Autotune and should be 'misclubsocial.com')
* Your Site URL is not set correctly (again, autotune should have set this to '
www.misclubsocial.com')
* Your app is in Sandbox mode. If you edit the app settings on Facebook, check for that setting.
Your SSL cert shouldn't have anything to do with the login process since I'm trying from your non-ssl site and still seeing that problem.
Let us know if that helps narrow things down,
Alex
