I am entering new pages that are children to children. When I do, I get this error:
WordPress database error: [Unknown column 'none' in 'field list']
INSERT INTO wp_post2cat (post_id, category_id) VALUES (240, none)
Warning: Cannot modify header information - headers already sent by (output started at /homepages/0/d144193462/htdocs/texas-fire/blog/wp-includes/wp-db.php:104) in /homepages/0/d144193462/htdocs/texas-fire/blog/wp-includes/pluggable-functions.php on line 272
(i don't know what a 'backtick' is, sorry)
Strange thing is that the page is still created, and works just fine. Here is the site for reference. The pages I am dealing with are under the 'departments' link, in Region 7.
