Missing div tag, causing problems

This is giving me a hard time.. I've used divcounter.jhousemedia.com and it tells me that there are two div tags missing. What I don't understand is that both of these posts are exactly the same, so I'm not sure why this is happening..

Here is a post where 2 div tags are missing:

On the 2nd one, the footer is floating on the top of the page, and the sidebar is on the bottom. Anyone know where or what开发者_JAVA技巧 div tag I am missing? Both are the same posts generated on the fly by wordpress so I don't understand this

Thanks in advance!

You're missing closing DIV tags for
