tried sub theming, now layout is messed up

Howdy. I followed the instructions here:

http://opensourcecms.pro/drupal/howto-drupal-7-sub-theme-creation-step-b...

And got *some* change to the look of the site, but not what I wanted, so I made TouchPro the default theme again and moved my theme files from themes/ to /tmp/

But now the entire site comes up inside what I think was once the content region:

http://gyazo.com/1be9f86b9300b79c947cca5e51896fe8

... so something must have gotten cached? I've tried Performance --> Clear Cache and Enable / Disable "Aggregate And compress CSS files" but it doesn't change it.

What should I do?
