 * Hi there!
    Whenever I create new article or a page I receive this error message:
 * > WordPress database error: [Table ‘detoam_wrdp1.wp_categories’ doesn’t exist]
   > 
   > SELECT c.cat_ID AS ID, MAX(p.post_modified) AS last_mod FROM `wp_categories`
   > c, `wp_post2cat` pc, `wp_posts` p WHERE pc.category_id = c.cat_ID AND p.ID 
   > = pc.post_id AND p.post_status = ‘publish’ AND p.post_type=’post’ GROUP BY 
   > c.cat_id
 * The articles and pages do appear to be okay, but I just wanna make sure. my understanding
   is that I have to create that table in my database (it used to exist. until after
   update that is.) I just have no clue how I can do that.
