 * I’m not sure about the MAIN ERROR there, but for headers already sent, please
   follow this [guide](http://codex.wordpress.org/FAQ_Troubleshooting#How_do_I_solve_the_Headers_already_sent_warning_problem.3F).

 * The error is saying that it cant connect to the MySQL Server, I’d say its most
   likely a plugin given the error.
 * I’d strongly recomend you upgrade to the latest version of wordpress however,
   2.1.3 is unsupported and 2.3 was just released.

 * Oh ok! Good to hear! What plugin was it by the way? Google Site Maps? If so, 
   you need to upgrade your [Google Sitemaps](http://wordpress.org/support/topic/135160?replies=6)
   plugin to the [latest version.](http://codex.wordpress.org/Plugins/Plugin_Compatibility/2.3)
   Also, can you mark this thread [Resolved] then too, please? Thanks. =)
