 * Hello,
    I have recently switched to WP 2.3 and until an hour ago or so it was
   working just fine. But just recently while editing a post/page or posting a new
   one, I get the following error:
 * WordPress database error: [Table ‘wp_wpdb.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 ‘wp_wpdb.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/content/l/a/e/laemo/html/wp-includes/wp-db.php:160) in /home/content/
   l/a/e/laemo/html/wp-includes/pluggable.php on line 391
 * The url of my website is: [http://www.nmimsieee.com](http://www.nmimsieee.com)
   if you want to take a look. The post gets edited successfully, but I get this
   error instead of the page being redirected to the post/page list in the WP admin
   area.
 * Currently active plugins are:
    Akismet BBPress Integration BBPress Latest Discussions
   Dagon Design Form Mailer Dagon Design Sitemap Generator Democracy Polls Full 
   Text Feed Get Custom Field Values Google Sitemaps Maintenance Mode rc:custom_field_gui
   Search Meter Sidebar Login Subscribe to Comments Translate Widgetize Anything
   Wordpress.com Stats Wordpress Database Backup
 * I have disabled suspicious plugins, but it’s of no use. It was working fine until
   an hour ago.. any idea what could be wrong?
 * Help would be appreciated. Thanks in advance!
