Apparently, my friend’s host disabled php for a while, which led to the blog going down. It just got back up today, and after many tries to manually re-code the php of the files that got messed up with wp-cache, I gave up and decided to just totally re-install WordPress. It’s awesome that way because if you massively screw up, as long as you got stuff backed up, it’s alright (not that it’s encouraged, of course).
Anyway, woo, it’s back up now. Yay.
