Ultimate Facebook Not Working

Just like everyone else I installed "Ultimate Facebook" and it's not working. Specifically it's not showing the "login" button but only showing non-linked text instead, and it's not showing the "Like" or "Share" buttons on posts.

Here's the site...

I have tried disabling all plugins and reverting to the default theme... nothing works.

It's connecting to the API successfully.
I even tried setting up a new "facebook app" to make sure that wasn't the issue.

Since so many people are having this exact same issue it's pretty obvious it's something to do with the plugin.

Looking forward to a helpful reply.
