Facebook integration (Read 100 times)

I apologize if this has been discussed recently.  I searched, but I didn't find any recent topics on this...

Quite a while back, my runs used to post to my Facebook page.  Then a while ago, it just stopped.  I never really bothered to look into until now.  I "unlinked" my RA account on the FB preferences page, but when I try to re-link, it won't work.

Is this a known issue?  Is there anything I can do?  No big deal, since I've lived without for a long time.  But I just thought I'd ask.  Thanks...
