help – upgraded – now cannot Edit Posts or Add New Posts

i was using wordpress 2.7.1 and it was working fine (although highly outdated and lacking any new robust features).

i upgraded today to the latest and greatest 2.9.2
install went fine
i can log into wp-admin just fine
when i click on Posts and then Add New Posts or Edit Posts though, it all goes downhill quickly.

in the Add Post page there is simply no post editing box.

on the left of the screen there is still the navigation bar for wordpress (dashboard, posts, media, etc.). on the right of the screen is the “publish” box, post tags, categories, etc.

in the center of the screen, where the post editor should appear there is simply nothing. at the top it says “Add New Post” and immediately below that, where i should be able to type a new post, it’s simply blank. there is nothing there.

also of note, in this screen the tabs “screen options” and “help” don’t drop down when clicked. in all other areas of the dashboard both of those tabs work.

please help.

as a last ditch effort i uninstalled literally everything to do with wordpress from my site (via FTP). i created a new mysql database (v5.0) and restored my old database to this new mysql database. then i reinstalled wordpress (again via FTP) and started over with a clean slate. if you check my site (theworldforgot.com) you’ll see that it’s all of my content but in a completely generic/default layout.
