I am completely new (less than a week) to WordPress and I don't know what the following error message means or what I can/should do about it. It comes up about a third of the times I upload something but I have not yet found a consistent pattern. I don't think there is anything wrong with my connection.
WordPress database error: [Lost connection to MySQL server during query]
INSERT INTO wp_postmeta (post_id,meta_key,meta_value) VALUES ('11','_pingme','1')
Warning: Cannot modify header information - headers already sent by (output started at /homepages/12/d83843876/htdocs/word/wp-includes/wp-db.php:102) in /homepages/12/d83843876/htdocs/word/wp-admin/post.php on line 128
Hope someone can help
