Okay, thank you so much!!
Does it have anything to do with the customization upgrade wordpress is pushing with 3.4?
Appearance>custom takes me to a link that says $30 buys the CSS and fonts.
Question: are you able to download the CSS from ftp?
Hey thanks!
I actually found a solution.
Upload a new, unchanged .php file via ftp. The site was back online instantly!
Thanks for the pointer about what to post.
