[TYPO3] Typo3 Backend, Page tree has disappeared!

[Rod Naugler]

Hey all,

Just tried logging into my typo3 backend to work on some content and the
page tree has disappeared. Logs in fine. Left menu is fine. Right intro
is fine. CLick on Page and the center page tree area is blank. View
source shows a ton of stuff there, but none ever displays. Tried in
Firefox, IE6 and Epiphany. Still nothing.

Any ideas?
