CMS DB Error with new widget
 

I created a widget which needs a own db connection
so i created a php widget with following code:
[php]require_once DIR .'/userwidget.php';
and the files code is:
PHP Code:
$userdb = new vB_Database(vB::$vbulletin);

// hier die parameter anpassen
$connectiondata = array(
'db' => 'userdatabase',
'server' => 'localhost',
'user' => 'root',
'pw' => ''
);

$userdb->connect($connectiondata['db'], $connectiondata['server'], 3306, $connectiondata['user'], $connectiondata['pw']);
$user = $userdb->query("...");

Error i got:
