Garry,
No clue why it started working, or stopped in the first place. I'm not familiar with Simple SEO, but if you install it again, and JFBConnect starts acting up, definitely let us know.
As for pushing JomSocial status updates to Facebook, that's one thing we don't currently do. We're looking into creating a new plugin that will be included with JFBConnect to push different types of activities to Facebook, but it probably won't be available until the June timeframe. Hope this helps, but I understand 'sooner is better'.
Any feedback welcome, and best of luck to you!
