 * Hello everyone, I recently upgraded my blog to WP v2.3 and I receive the following
   error when I try to save/publish a post:
 * WordPress database error: [Table ‘auction3_wrdp1.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
 * Any ideas of how to correct this? It looks like a file added charaters to my 
   already existing database.
 * Thank you in advance!

 * Could be an incompatible plugin (or theme).

 * Yup, found that the Google Site Map plugin was causing the error. I wrote another
   post about login issues I’m having while trying to upload a pic. Any ideas? When
   I hit the upload button or publish button I’m taken back to the login page.
