Sidebar moved to bottom. I trashed the blog post that I did. This did not fix the issue. I followed all suggestions here: http://en.support.wordpress.com/themes/layout-issues/
I already had the box to fix checked. I didn't touch my sidebar since it was working properly last night before bed.
Perhaps I missed something or there is a temporary issue with the theme?
I don't know how to do CSS.
Not sure how to locate answer to issue, I think it comes in my email.
