Upgrade caused loss of Categories

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?

Micheal,

Can you help me out or lead me? I’m having a simular problem. My catagories are not working. Post don’t stick to them, and after creating a ctegory (and populating it with a post) it still doesn’t show up…

Please?

THANKS!!!

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…..

please help

…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?

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: https://www.ads-software.com/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?
