Layout problem with sidebar icons

Hi,

I’ve noticed a layout issue with the social media icons I have located in the sidebar of a site. On the blog page they are positioned fine in the sidebar and the sidebar renders correctly (see: englishlc.com/blog/). However, when I visit a blog post, the result is a corrupted layout with the tags/categories and sidebar misaligned (see: englishlc.com/more-conditional-forms/), and no social icons displayed after the post. I’ve not made any other changes on the site, and disabling the plugin resolves the issue. I can’t see any errors in the Firebug console, and in the page source I can see the javascript being loaded for the plugin.

Any ideas what could be causing this?
