Since the 3.0 upgrade, WordPress has asked me to update my themes, Magazine Basic and Sandbox (I didn't design the site, so I don't know how both were running at the same time). I finally caved today and it was a disaster. I just want go back to how it looked a few hours ago. I tried looking at the coding for older versions of themes and editing it accordingly, but that just made it worse.
Here's what my site looked like before: http://www.regrettablesincerity.com/wp-content/uploads/2010/07/oldtheme.jpg
Here's what it looks like now: http://www.regrettablesincerity.com
I have a memory of also incorporating the Magazine Three Column theme, but I don't seem to be able to fix any individual thing. I do have backups from June 21st, at least as an exported xml file, but I can look for more backups if others have suggestions.
Any help would be most appreciated.
