Facebook Widgets have dissapeared

Hello!

I am one of the administrators of https://www.boldmagazine.ca and from yesterday, the facebook aplications on our site have dissapeared. On the bottom right we had the “Styled Facebook Like Box” and is not displayed, and in the featured posts we are missing the facebook icon to like the posts, but we still have the twitter and G+ icon.

Is very strange, Does anybody know what happened? Is there any way I can fix it?

Thank you so much in advance!
