I had the same error:

I changed line 1589 (or somewhere around there) in wp-db.php from `return preg_replace( ‘/[^0-9.].*/’, ”, mysql_get_server_info( $this->dbh ));` to `return preg_replace( ‘/[^0-9.].*/’, ”, mysql_query(“select version() as $this->dbh”) );`, and that error stopped. Try doing that
