Database Error when Publishing/Editing

I am running WordPress 2.0.2. I get this error when I am using Windows OR Mac, and Firefox, Safari, or Internet Explorer.

Here it is. Whenever I publish a new post or edit an existing post, I get the following error. (After clicking “Publish” (or “Save”), the wp-admin page sits there for about 2 minutes, then produces this error on post.php.)

………
WordPress database error: [Lost connection to MySQL server during query]
INSERT INTO wp_postmeta (post_id,meta_key,meta_value) VALUES (‘314′,’_encloseme’,’1′)

Warning: Cannot modify header information – headers already sent by (output started at /home/content/d/r/i/drienne/html/wordpress/wp-includes/wp-db.php:102) in /home/content/d/r/i/drienne/html/wordpress/wp-admin/post.php on line 60

…………

This error does NOT occur when I delete a post or save one as a draft (unpublished), and does not occur when a comment is left either.

Line 60 of post.php says… “header(“Location: $location”);”

I have emptied my cookies and cache, lowered my security settings, tried it with and without firewall, with and without antivirus.

Someone suggested to me that I have a corrupted database, so I backed up my tables, deleted my database and started a new database. I loaded the tables in to the new database, and the error still persists.

I am running one plug-in, called “Did You Pass Math?” which is on the wp2 compatibility list I believe. I have tried turning it off and that doesn’t make the problem go away either.

I emailed my hosting service (godaddy.com) and asked if they could restart the server my db is on, but they said that was not an option.

This error began out of the blue approximately 1 week ago. I did not edit, replace, or manipulate any of my files, it just randomly started. I upgraded to WordPress 2.0.2 several weeks ago, and it was running perfectly until now.

I want to note that while I do get this error message every time I publish or save, the changes/new posts DO appear on the blog and are saved in the tables. But this error.. it’s inconvenient and irritating.

Can someone help me?
