    - Lost Categories after upgrade -

    Situation:
    I upgraded from WordPress 2.1.1 to 2.3.3.

    I noticed the second side column of my 3-column theme was missing. After reading this post, I checked my database and found Categories tables were missing.

    Solution:
    (Note: I use phpMyAdmin via Cpanel)
    1. Locate database files that you backed up before the upgrade.
    2. Create a new database, add original admin user to it, and upload backup files to it.
    3. Edit wp-config.php to point to new database name.
    4. The site should be working at this point.

    But you want to get back the original database name.
    4. Delete files from original database (do not overwrite).
    5. Upload backup files to original database.
    6. Edit wp-config.php to point to the original database name.

    I just upgraded from 2.2.1 to 2.3.3 and lost both categories (the database is completely gone; everything is now uncategorized) and my blogroll (the blogroll still exists via the admin panel though).

    I followed the instructions to the letter and have read through this thread and am still at a loss as to what to do. Because I am a moron possibly.

    I did back up the database and the entire blog file and deactivated all the plugins before performing the upgrade.

    What do I need to do to rescue categories and the blogroll? Any help would be appreciated.

    Hi

    I had the same problem. I installed without plugins deactivated, and my database was not upgraded correctly (i.e. wp_categories remained, and wp_terms, wp_term_taxonomy etc. were not created).

    Initially I reverted the db_version manually as per the advice above.

    However, what fixed the problem in the end was changing my wp-config file to use an admin account. Previously I was using a default account that could not drop tables or create new ones. Could this solve others' problems above?

    If I try to add a category it gives me the "something strange happened refresh the page" message and when i refresh nothing happens.

    I also tried adding a category (or tag) by editing a post but that doesn't work either.

    All my categories right now are missing.....

    ...and may i join the list of this merry band...
    I have tried evertying (i think!) but to no avail.
    i think i may have not disabled plug-in's when upgrading.
    I upgraded to 2.2 and lost all my categories, and was unabel to add. upgraded to 2.3.1 and to no avail with teh same error messages as member above.
    i have just upgraded to 2.5 (beta) and at least this is leting me add new categroies, so perhaps I need to go back and do them all again..
    however, i'm a bit worried as all the orginal categroies are still in my SQL database, along with number of posts they are assocated with, just not visibile...
    any ideas?
    Joe

    Hmmmmm,
    no responses - i wonder if this thread is lost momentum...
    anyhow, an update from me:
    now i've managed to add categories, i've double cheked the sql database using PHPMyAdmin plug in for wordpress - and the new categories have nor appeared in the database...
    ...so, i'm left puzzled, where have the new categories gone i wonder?
    ...if i back up my database, will the new categories be remembered?
    I'm wondering if I need to delete teh old wp_categories database...

    any clues (to a SQL complete novice) anyone?
    Joe

    Same problem: http://wordpress.org/support/topic/168546?replies=1 after update to 2.5. All posts are now uncategorized.

    Checking my bolg today I get this message instead of any actual category links, "No categories."

    When I go to manage > categories, no categories are displayed.

    When I go to Manage->Posts, all Posts are marked as "Uncategorized". When I do click on any given Post the Categories panel does properly indicate the categories that it belongs to.

    I have not upgraded recently and am using v2.5.

    Can anybody tell me what's going on?
