Google Sitemap and Ultimate Tag Warrior Plugins Errors

Today when updating an existing "page" I got the following error message:

"WordPress database error: [Table 'mytynesi_.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

Warning: Cannot modify header information - headers already sent by (output started at /home/mytynesi/public_html/wypov/wp-includes/wp-db.php:160) in /home/mytynesi/public_html/wypov/wp-includes/pluggable.php on line 391"

After some searching on the http://www.wordpress.org Forums it was recommended to deactivate all my plugins and then reinstate each one individually. I then tested the save function on my page after each reactivation and I found that both Google Sitemap and Ultimate Tag Warrior Plugins had been responsible.

The reason for the sudden error messages when they had both been working fine in the past is that I had upgraded to wordpress 2.3.1 and both of these plugins are not compatible with it. I am in the process of upgrading the plugins to work with my new wordpress version.

I know I will keep an eye out for that one next time.
