I'm getting the flollwing error when posting anything on my blog. The posting actually does show and "post". But why the error message?
WordPress database error: [You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1]
SELECT * FROM wp3_post2cat WHERE post_id =
Warning: Cannot modify header information - headers already sent by (output started at /srv/www/htdocs/wp3/wp-includes/wp-db.php:102) in /srv/www/htdocs/wp3/wp-admin/post.php on line 59
Any help is appreciated.
