I've tried searching, but I'm not sure what you call the panel where you write and edit posts and I didn't turn anything up.
I just noticed that my Advanced Editing features (e.g., custom tags, slugs, preview, delete, etc.) are gone. They simply don't show up in the editing/writing screens. I have "Advanced" checked in Options. I've disabled the following plugins thinking they might be the culprits, but to no avail:
I also reuploaded the file post.php from a fresh distro (1.5.2) of WP.
Any ideas? Here's a screen shot, note it stops dead right after the writing area.
Thanks and Merry Christmas, everyone. I don't expect an answer today but I'd sure like to know what happened to the rest of the admin panel eventually!
