Facebook Plugins/Widgets not Showing

Hi, all! Going nuts here.

Just recently opened a site (cinevasco.com), and, although the facebook like box widget was working at first, at some point it suddenly stopped working. Title shows, but not the actual widget.

I deactivated all plugins – didn’t work.
Used a link to a different facebook page, just in case – didn’t work either.
Used various plugins and widgets that use a facebook like-our-page-box sort of mechanism, and none of them seem to work (you can find two plugins on my site – none of them work).
Have no idea what the heck is wrong with it.

Now, just want to note that ‘like boxes’ (as in, ‘I like this post’) works. It’s anything that has to do with linking a facebook page.

I updated my site to Spanish (if that helps at all).

Hum… yeah. That’s about it.
What do I do?! Most of my visitors are from Facebook and I need it back up and running asap.

Thanks a bunch!
