Ugh - Look Away!

I'm sorry the blog suddenly got all ugly, and I'm working to fix it.

I was investigating how to better customize my template, and in the process, clicked on "revert to classic template."

When I did so, I got a pop up telling me that I would be able to restore my current template.

But how???

I've tried uploading the backup that I'd saved.

I've tried reselecting the template and reapplying my customizations.

When I preview it, I see the right version, but when I go to it for real, I get this awful, ugly, "classic" template.

HELP!!!
