 * Greetings,
 * I am using WP Default v1.5 and now all of sudden when I try to open the only 
   category listed I receive the following error message(path name changed for illustrative
   purposes):
 * Warning:Invalid argument supplied for foreach() in /home/usr/public_html/blog/
   wp-includes/functions.php on line 283
 * Also the following is another WP error message supplied:
 * WordPress database error: [Got error 12 from storage engine]
    SELECT DISTINCT
   YEAR(post_date) AS `year`, MONTH(post_date) AS `month`, count(ID) as posts FROM
   wp_posts WHERE post_date < ‘2006-09-02 18:22:56’ AND post_status = ‘publish’ 
   GROUP BY YEAR(post_date), MONTH(post_date) ORDER BY post_date DESC
 * Not exactly sure what happened here because everything was functioning fine and
   then out of no where this started.
 * Any help with this would be appreciated.
 * Regards,
    rozmo
