Sidebar and content missing on post

In the most recent post I wrote, the sidebar is missing, and half of the content is as well! It seems the content is not being wrapped around the sidebar, and the sidebar just isn’t there.

I am not much of a coder, so any tips on where I look in the CSS or whever this stuff lurks would be greatly appreciated.
Thanks!
