Facebook Login showing url blocked

Can you post an image or more details about the exact error message you're receiving and how you're seeing it? Does it happen right when you click the Facebook login button, or after you enter your credentials?

We'll gladly help investigate further, but your sounds like it may be difficult to recreate. I just went to your JomSocial Home page and clicked the 'Facebook' button. It properly brought up the Facebook login credentials, but I'm not sure if that's further than you get or not.

Thanks,
Alex
