I didn't know Magento had it's own backup and restore capability, so I did a backup of the site on the host.
You guessed it, I messed up the page, but I don't know which folders in the public.html folder refer directly to the display of the web site. Is it just app?
Fumbling around and I'm in a several hours long, hateful loop of copy and delete. Please save me! I'm trying to do a favor for a friend, and it's all gone wrong.
