Sidebars moved underneath content?

Hi, I did a search of the boards for this but did not find a solution that worked for me.

My blog is set up as 3 columns: content, sidebar 1, sidebar 2. I’m using Thesis theme.

All the sudden my 2 sidebars and multimedia box are underneath my content. I haven’t done anything different that would change this. It started happening after I wrote and previewed my latest post. This is only happening on the Home page though–not any of the other pages.

I tried deleting my latest post, making all the pics on my home page smaller, and going through all the posts and hitting “close tags”–none of these things work.

Here is a link to my blog: https://budurl.com/upfe

Any ideas how to fix this? Thanks.
