Imported blog page layout messed

http://uma.lohray.com/weblog/moots-part-ii/

is a blog I imported from blogger. The front page is fine, but when one clicks to read a blog post, the end of the post has parts of the right side bar widgets. I tried different templates, but the problem persists. I exported the blog as .xml and tried to see the data in the CDATA section to look for malignant tags, but it seems fine. Any new posts I make from wordpress are also messed in the blog page.

I am at my wits end on fixing this 🙁

I am running a multi-site network.
