Follow buttons not displaying

Hi,

I have enabled your plugin on my site http://www.abolishion.org. The FB like and email buttons display on each page but the Follow button does not.

I have set the follow button to show after the post on archive, post and page using Standard layout, not showing faces and dark color scheme.

Can you help on why this would not be displaying?

Thanks

Leanne
