Widget are not showing on website

Hello,
I have latest versions of WP and FB plugin.
I’ve added the APP ID (117144215118272) and APP Secret. But my widgets are not appearing on my website (www.rrapl.ro). It worked in the first week, or 2, and now it’s not.

Whatever I do, the widgets are not appearing (showing). If you inspect the elements, you can see the code, but the space is just blank.

I’ve added a facebook send button in the Bottom sidebar (example: http://www.rrapl.ro/site-pentru-poli…ce-a-romaniei/)

And another one, a facebook like box, in the home page, on the right sidebar where the blank space is (www.rrapl.ro)

Both of them are not showing. I tried to deactivate all plugins, reinstall facebook plugin, but nothing works.
