Sidebar showing up at bottom of page … wrong place, not in sidebar area

Hmmm… okay, this site has been up for a while, beautifully… today, I go take a look at it and any page that has the right sidebar is all messed up. Sidebar is showing up between page content and footer. Help?

Here’s a link to one of the pages that uses the sidebar (most do, except home page, which looks good because I used full width page and columns, not a sidebar): http://davidessel.com/services

Thank You!
