我收到此错误消息

 Fatal error: mysql error: [0: Connection error to server 'localhost' with user 'use_online'] in CONNECT(localhost, '****', '****', use_home) in /home/usr/public_html/libraries/adodb/adodb-errorhandler.inc.php on line 81

我正在使用 adodb

我的代码

require_once($config['basedir'].'/libraries/adodb/adodb-errorhandler.inc.php');
require_once($config['basedir'].'/libraries/adodb/adodb.inc.php');

$conn = &ADONewConnection($DBTYPE);
$conn->NConnect($DBHOST, $DBUSER, $DBPASSWORD, $DBNAME);
@mysql_query("SET NAMES 'UTF8'");
$sql = "SELECT * from config";

$rsc = $conn->Execute($sql);

它工作正常但是赢了我搬到新服务器它给了我上面的错误

更新

adodb.inc.php 代码.......................... ............
