I upgraded from 1.5 to 2.0.2 yesterday. Now when I publish posts, the posts appear, but I get the following error:
WordPress database error: [Lost connection to MySQL server during query]
INSERT INTO wp_postmeta (post_id,meta_key,meta_value) VALUES ('282','_pingme','1')
Warning: Cannot modify header information - headers already sent by (output started at ../html/wp-includes/wp-db.php:102) in ../html/wp-admin/post.php on line 127
Anyone have any ideas?
