Definitely good of you to bump the thread. I remember the request, but obviously, we didn't come up with a solution. Apologies for the delay.
Our demo site is using 3.0.2, and when I look at your FB profile and your JomSocial profile, I'm seeing that they match up. I don't really want to paste both links here (even if they are fully public info), but I'll put your activities, which in both is:
Veel teveel om op te noemen
Can you try updating your activities, even just slightly, and log into the demo site? Even if you get the "Can't get your information" error, if it updates, that will help us track down the issue. Let us know the results.
Finally, could you send us a link to your site that isn't working? I looked through the other thread and couldn't find it. We have a few FB accounts that are set up in known ways that have failed in the past. Would like to test on your site to see if we can catch something obvious. If you want to Private Message us the URL (so it's not public) that's fine.
Thanks
