Please see http://www.fattyacidtrip.com. You'll notice two weird things about it that appeared all of the sudden:
1) The sidebar font is now huge.
2) From the 4th post on down, the font size changes in the title of the post.
The weird thing is that the sidebar displays fine when you click on one of the categories. See http://www.fattyacidtrip.com/category/faq/ as an example.
Here's the strangest part: The problem remains even when I switch themes.
I rolled back all my files from a previous backup, yet the problem remains, as well.
Do I have a ghost inhabiting my server? What gives?
Please, please help. My site is live and very broken.
