   Hey guys...I've been running my site on WordPress for about 5 months and today it just stopped working. When accessing the admin panel, I get the following error:

   WordPress database error: [Lost connection to MySQL server during query]
   SELECT ID, user_login, user_pass FROM main_users WHERE user_login = 'admin'

   Warning: Cannot modify header information - headers already sent by (output started at /www/t/tipmonkiesco/htdocs/wp-includes/wp-db.php:98) in /www/t/tipmonkiesco/htdocs/wp-includes/pluggable-functions.php on line 109

   I already checked for extra whitespaces, I analyzed all the tables, etc. Anyone have any ideas?

   Hi

   I think that you've just installed a plug-in and that cauased the problem , and if my guess is right , the problem is that the plugin file has some "empty spaces" before <?php or ?> tag,

   Is my guess right?

   Actually, the original error is a hosting issue which has caused the blank space, and thus has caused the other errors to appear.

   WordPress database error: [Lost connection to MySQL server during query]
SELECT ID, user_login, user_pass FROM main_users WHERE user_login = 'admin'

   The above error clearly states that WordPress has "Lost [the] connection to [the] MySQL server during [a] query". This can either mean that your MySQL server is either unstable, or its connection threshold is set far too low. You should contact your hosting provider.

   You are right macmanx, It's something related to hosting problems ,

   Try what is suggested in this thread -

   It's whitespace, which you say you've already tried, but just make sure you checked the wp-blog-header.php file.
