Thanks for letting us know what browser your using. The site looks offline, so I can't test anymore.
Can you check the extensions / add-ons you have installed in IE and Chrome and disable them? There are some add-ons that conflict, or are intentionally meant to disable, social network feature on websites.
Beyond that, are you behind any sort of corporate firewall or anything else that would block features? Are you logged into Facebook when you're trying, or not?
Not sure what else to ask, but hopefully that helps narrow things down.
Thanks,
Alex
