categories corrupted after 2.9 upgrade (9 posts)

    Hi, when I installed wordpress 2.9 over 2.8.5, all posts were marked as Uncategorized. The categories still exist, but not everywhere. Link categories are also broken.

    I then deleted the mySQL database, installed 2.9 and ran install.php, and uploaded the XML file. To my surpise, the categories are still broken.

    Here are some symptoms:
    - posts are all uncategorized
    - the link widget does not work
    - categories.php does not show any category
    - adding a category works, but no posts can be associated to it
    - categories are visible under "Most used", but not "All categories" in the post edit form.

    How to debug this?

  2. Were you using some sort of category plugin?

    Try to backup from an earlier restoration point.

    @Ipstenu: no, and I also disabled all plugins.
    @neodan: I didn't backup the mySQL database. But I did a clean upload from the XML onto an empty database, and the problem persisted. Assuming that the XML import works, I could roll back to 2.8.5.

  5. I would first try to re-upload the WP files. It can't hurt at this point, but it sounds like something in your DB got weirded... Sorry, my brain fails me.

    I had also tried 2.9.1RC, clean install.

    Thanks guys, I'll let you know if I figure it out.

    Thanks ibnuasad, I tried that and similar things including changing the options, but no go.
