Error Updating Page

[cdharrison]

Just upgraded to the latest version (WP 2.3 RC1) and got the following error when I tried to update an existing page:

WordPress database error: [Table 'db16179_cdharrison.wp_post2cat' doesn't exist]
SELECT cat_ID AS ID, MAX(post_modified) AS last_mod FROM `wp_posts` p LEFT JOIN `wp_post2cat` pc ON p.ID = pc.post_id LEFT JOIN `wp_categories` c ON pc.category_id = c.cat_ID WHERE post_status = 'publish' GROUP BY cat_ID

It must be a plugin causing your error, because the wp_post2cat table has been removed as of 2.3-RC1.

Try disabling your plugins one at a time and then editing a page. Once you've found out which plugin is causing the error, do contact the plugin author and let them know their plugin is incompatible with 2.3.

I agree, I have RC1 on my home server, it works fine for me. Basically the categories, post2cat, link2cat tables have been removed and replaced with other ones, so it is likely a plugin is causing the problem, check with the plugin developer and get them to update for Wordpress 2.3.
