New Post: Facebook box disappeared

Hi, we had a Facebook box put in that showed our recent Facebook posts on our websites. When I added changes to a box above it in the same frame, the Facebook box disappeared, even though I didn't make any changes to it. I don't get any error message, it just doesn't show up.

Website - www.will-law.org (should be appearing on the bottom of the right-side frame).

Code:

<div class="fb-like-box" data-href="http://www.facebook.com/pages/Wisconsin-Institute-for-Law-Liberty/191561687596446" data-width="260" data-show-faces="false" data-stream="true" data-header="true"><br /></div>
