Blog Layout Error

the Joomla Blog layout is causing the page to look odd and right modules to fall below main content area.

Any ideas?

I am using K2 for the directory and the category blog layout in K2 does not do this

Some <DIV> tag is not closed so main area sucked in right column. You need to check articles and other things you have in main area to look for that.
