After writing a post and clicking "save" I am returned to the blog page (instead of staying in admin) and the post isn't saved. Same thing if I click "publish" -- sends me to the blog and the post isn't there. If I go to "manage posts" the post isn't listed there either.
Funny because I was just posting about 10 days ago (2009-05-11 was the latest post) and everything was working fine. I haven't changed anything since then.
Anybody else experiencing this? Any ideas?
