Support » Fixing WordPress » New categories 404

  • Scott Fennell



    We are running wpmu. We have about 500 live blogs on our network. Several of our sites have started to see the same problem recently: The category archive page for newly created post categories will 404.

    It’s not that it says no posts are found for a particular category, it’s that it thinks the category itself doesn’t exist.

    The problem happens…

    1) Regardless of theme
    2) Regardless of plugins
    3) Regardless of category slug
    4) Regardless of # posts assigned to the category
    5) Only on newly created categories (we noticed it about a month ago and it’s still happening — and seems to be spreading across our network)
    6) On the front end — you can browse categories just fine on the back end.
    7) Regardless of how many times I flush the rewrite rules by changing permalink settings
    8) On any permalink setting other than default. If I go to default permalink structure, it works fine.
    9) Only on categories — tags work fine.
