Kaptinlin Themes Support

So far I haven't run into any issues with the Share This plugin.
It has always shown up on pages and blog posts as I wanted it to.

But after my upgrade from an old Striking version to the most recent it doesn't show up in blog pages and posts that are on page #2: http://www.georgelangenberg.com/blog/page/2/

What file should I edit to fix this?

Thanks, George
