* Google Sitemaps 2.71 Breaks WordPress 2.3.1

Disable Google Sitemaps to avoid errors in WordPress 2.3.1.

I just upgraded from WordPress 2.2.3 to WordPress 2.3.1. I’ve had problems with two plugins.

Better Blogroll 1.13 does not work with WordPress 2.3.1. The widget renders raw PHP instead of the desired HTML output. So I’ve disabled Better Blogroll 1.13 for now.

Google Sitemaps 2.7.1 does not work with WordPress 2.3.1. But this failure is not as obvious. If you use the default theme, disable all plugins, enable Google Sitemaps 2.7.1, and then try to edit and save an existing post, you’ll get this error (where “example” is the name of your MySQL database):

WordPress database error: [Table 'example.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

WordPress database error: [Table 'example.wp_post2cat' doesn't

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

'publish' GROUP BY cat_ID

Disabling Google Sitemaps 2.7.1 fixes the problem.
