I'm running a CVS copy of WordPress. Sometime during the last couple of weeks, it seems that editing of old posts has stopped working. I can go to the edit screen and edit what I want, but it's not updated -- if I view the post I get the old version. My Apache logs show a successful POST to wp-admin/post.php... looks like WordPress simply isn't storing the changes in the database for some reason.
Anybody else have this, or is this some local weirdness? Annoying, wherever it came from :/
