 * WordPress database error: [Unknown column ‘user_level’ in ‘where clause’]
    SELECT
   ID FROM wp_users WHERE user_level > 0
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/coralsea/public_html/wp-includes/wp-db.php:133) in /home/coralsea/public_html/
   wp-includes/pluggable.php on line 331
 * The above come up on a blank web page every time I publish a post but the post
   still gets published without a problem. I’ve looked through my plugins but can’t
   seem to find the source of the issue> Any idea’s?
