 I’ve been running into problems ever since I upgraded WordPress to 2.x
 (not sure if it was 2.0 or 2.1) with new posts. The first time a new post
 was was loaded into the browser, the server kicked out this error:

 PHP Warning: mysql_affected_rows() [<a href='function.mysql-affected-
 rows'>function.mysql-affected-rows</a>]: A link to the server could not be
 established in /Users/alex/Dev/SilverSpider/site/wp-includes/wp-db.php on
 line 183

 My old wp-config.php contained some lines that are not included in the 2.x
 wp-config-sample.php:

 $server = DB_HOST;[[BR]]
 $loginsql = DB_USER;[[BR]]
 $passsql = DB_PASSWORD;[[BR]]
 $base = DB_NAME;[[BR]]

 As the upgrade instructions specifically state that one shouldn't delete
 wp-config.php, nor do they provide any direction on modifying it
 accordingly, this could be a problem on a lot of sites.
