Jomsocial 3 and JFB Connect

Something's definitely not right. Can you verify the following:
* The JFBConnect Authentication and User plugins are enabled.
* In the JFBConnect -> Configuration area, set the "Debugging Mode" setting to "On". Then, when you login, there may be an additional error message that will explain the problem.

Beyond that, I'm not sure of what would be causing your problem. If you still can't get it going, let us know, and we'll help however we can.

Thanks,

When I run the Autotune - Error Check tool on your site, I'm seeing the following error:

Test: Facebook Javascript library inclusion
Fail: Another Facebook extension is installed, including the Facebook Javascript library, and may conflict.

That's a valid error because another inclusion of Facebook's sdk.js Javascript library is being included on your site. That needs to be removed.

I tested by switching your template to Beez5 from "My Default Style (Protostar)" and the authentication does work. So, it seems like that extra inclusion, or some other modification that has been made to the template, is causing the problem.

I hope that helps, but if you get rid of that extra inclusion and still have issues, let us know.

Thanks,
Alex
