Support » Fixing WordPress » PingBacks Give 404

  • I’ve updated from 2.0.2 to 2.1.2 recently and have the following problem.

    I then wrote a post, describing the problem at

    And got a 404 when I included one of the same URLs. Being a novice at this I can only assume WordPress automatically tries to PingBack any URLs included in the entry. There doesn’t seem to be a problem with ordinary links though, as I had no problem linking to a web page (.cfm) and a PDF (.pdf) in other posts.

    Any ideas what’s happening?
