Your Facebook Like Box shows up fine for me. I once had this problem, though, and it was caused by a Safari extension called Ghostery, which was blocking the Facebook script that needed to run. So check for conflicts like that. Try another browser, too.
Hmm, right you are. Haha. Sorry, should have thought to check in an alternate browser myself. The problem is in Chrome, but Ghostery has caused a lot of problems in FF for me in the past. Thank you for responding. Cheers
