Wordpress 2.6.2 categories ?

I recently upgraded one of my blogs to 2.6.2 and suddenly found that all my categories had vanished from the categories.php page ( In Wordpress Admin). The categories page neither shows the name, nor the description.

I've tried repairing the database, as well as tried to use Lester Chan's database repair plugin.

The categories do not show up on the main page of the blog either, and the same goes for the post ( Posted under ____)

Anybody who had to face a similar problem and managed to solve it successfully ?

 

Have you tried to change the theme? (the problem is also in the WP admin anyway)

Anybody???

 

Same theme.

Infact I'm using the default Wordpress theme for that blog.

 

This is a common bug if you upgrade from a blog that was originally (I think) version 2.3. The categories are still in the database but need to be manually edited to match what the new version of WP is calling them. Here is a link that should help: http://blog.cumps.be/wordpress-26-upgrade-fix-missing-categories/

 

Thanks for the link.

Took me around half an hour to clean it up, and that was a small blog

 

Doh, i just recently upgrade my blogs to 2.6.2 , i hope this won't happen to me. I heard from my friend that it miraclely vanished the category and the tags that come with it after 2 weeks.
