On the page you link to is the following code, which looks to be coming from jReviews:
jQuery(document).ready(function() {
jreviews.facebook.enable = true;
if(!jQuery('#fb-root').length) jQuery("body").append('<div id="fb-root"></div>');
jreviews.facebook.init({
'appid':'278767145515654',
'optout':1,
'publish_text': 'Publish to Facebook'
});
});That block of code is attempting to re-initialize the Facebook Javascript library in a way that is incompatible with the new authentication scheme that Facebook has required since December of last year (which JFBConnect of course uses). You'll need to determine how to remove that block of code, and it will likely fix your issue. Once it's gone, if you still have problems, let us know and we'll investigate further.
Thanks,
