Beginning this evening, I can no longer publish new posts on my blog at http://www.stephendanko.com.
I write a new post and click on "Publish" but nothing happens. The new post does not even show up on the list of posts. If I try to edit an existing post, everything seems to proceed normally, but when I click publish, the changes have not been incorporated.
Furthermore, it appears that comments have stopped coming in. I usually get 1000+ spam comments per day, but that's completely stopped.
I called my host (Yahoo! Small Business). They said they can't see anything wrong and suggested that I contact WordPress.
I'm using WordPress 2.0.2.
