[To begin, I know that I am one of dozens of people who have posted about this same problem, but as I scoured all the other requests, none were able to fix my problem.
Also, I feel I should add that my code 100% validates XHTML and CSS and that when the sidebar broke off, I was trying to change the background image that repeated down the page, so I was baffled that I couldn't even undo it.]
Ahh... so all that said, I'm hoping someone can tell me where I went wrong. I'm stumped, and crushed, as all was going along so swimmingly before this.
Theme was: Orchid at one point, but it's been changed a ton.
