I am getting this error when I attempt to post a new article:
WordPress database error: [Lost connection to MySQL server during query]
INSERT INTO wp_postmeta (post_id,meta_key,meta_value) VALUES ('338','_pingme','1')
Warning: Cannot modify header information - headers already sent by (output started at /homepages/10/d107237466/htdocs/blog2/wp-includes/wp-db.php:102) in /homepages/10/d107237466/htdocs/blog2/wp-admin/post.php on line 60
I followed the advice (or tried to) in the trouble-shooting guide, but I could find no extra "white space" on line 102 of wp-db.php
My posts still publish ... but I get that error every time. Also, my header file in not displaying. This only happened after the upgrade.
Any help would be greatly appreciated.
