I have it working for the individual post, because I took out all the structure of the permalink and only have postname.html
If you click on the category link "web design" on the right, poof, there goes the menu. If you take out /category/ from the URL, even though it returns a 404, the menu comes back.
So I have narrowed it down to the levels deep the URL is. However, I have no idea how to fix it!
