Looking at the source on your page, I see that JReviews is also including some Facebook code on the page. Could you please try to disable the FB options in JReviews.
jreviews.fb = {"appid":"1536563263271652","og":true,"xfbml":true,"optout":true,"post":false};
Also, when is this API error occurring? On the front-end when you click on a Facebook button? What specific URL?
