SC Login not working?

Yup, it's a bug. We're in the process of reporting it now.

What we're seeing:
* If a user visits your page and is already logged into Facebook, but button does not appear (you see a loading indicator quickly)
* If you aren't logged into Facebook, the button appears and should log you in normally after you use it to log you into Facebook.

Please let us know if you see different behavior. We will post back here once we have the bug report for Facebook finished so that you can say "Me too" to it to increase it's priority.

Thanks,
Alex

Just submitted the bug report. Please use the "Does this repro describe your issue?" link (Click Yes) and put in your details.

Leaving a comment is good too if you have more information, but the Yes link is critical to get Facebook's attention.

Thanks, and please keep this thread, or the bug report, updated with anything you find.

Ludwig,
It seems that FB isn't triggering some of the things it normally does when a user clicks the FB button (that JFBC relies on).

However, if you enable "Automatically Login Facebook Users" within JFBConnect's Login/Logout area, it helps work-around this issue.

That's because:
1) It will log users in using an alternate method that seems to be working
2) It also seems to be working if a user visits your page that has already approved your app by simply logging them in, instead of 'hiding' the button from them.

If you already have seen the blank button though, you may need to clear your cookies and browser cache for the auto-login to work.

It's not the optimal solution, obviously, but it's something you can use for now to help the situation. Please let us know you're experiences, and thanks for 'signing' the report!
