I got a 404 error when viewing category pages until I went to my Permalink Options page, without clicking the Update button the problem was resolved. Strange, but it works now so thanks for this plugin!
The same goes for me actually, I sleep better when there's someone in the house with me than when there isn't. Having migraines must suck, I'm glad I've never had them. Hope your sleeping problems all go away! Take care.
I've had this problem in the past. Adding another div within your main div, then adding the padding to that div (the new one) should work, at least it did for me. Hope it works.
