Why won't the Facebook Like button show up?

Hello,

I installed and set up your Floating Social plug-in yesterday, and it has been mostly worry free. However, while the Twitter and Google + Share buttons appear just fine, the Facebook Like button refuses to load and a blank space is left in the floating sidebar as a result.

I' updated to the latest version of WP, and I've tested the plug-in on multiple themes, including Twenty Eleven, but nothing seems to remedy the issue.

I'm currently developing a blog locally using Inspire (http://themeforest.net/item/inspire-a-multipurpose-masonry-theme/4023580) as my primary theme.

Any help with this issue would be greatly appreciated.

Thank you.
