Okay, I just found my answer on the JomSocial site - I had posted there a couple weeks ago and didn't notice they had replied to the thread. Here's the response and it works! Sure enough, I had 2 Joomlart plugins active and as soon as I turned them off, my top page Facebook worked great.
From JomSocial forum:
Re: facebook connect of Hello me module not working
I had a look at this and it actually had nothing to do with the template, but rather two of the Joomlart plugins (JA Facebook Share and JA Facebook Like It). These were the cause of the conflict because they were loading the Facebook javascript a second time. Once these were disabled, Jomsocial's F Connect works correctly again. Please test this again on your end and let us know it its working correctly.
Cheers
I still like your Facebook feature set better, so I'm happy I spent the $50 and now I can go enjoy my supper and stop pulling my hair out!
