Facebook "Like" Doesn't Work

Hi,

For some reason, when using Floating Sharebar, everything works except for Facebook “Like” box. It doesn’t show the actual number of likes — instead in shows 5.6m at all times — and whenever you hover over the “Like” button, you get “Welcome to Facebook” message. So instead of liking the article, at the end you’re liking just Facebook, or something.

Any suggestions, tips, advice on how to fix it?

I re-installed it, didn’t help. Thanks!
