@chan115117 Did anything get added to the database?

You can create the config file manually by creating config.inc.php in /system/assistants/

<?php
$settings['DB_SERVER']= "mysql_server_address";
$settings['DB_NAME']= "db_name";
$settings['DB_USERNAME']= "db_username";
$settings['DB_PASSWORD']= "db_password";


$settings['COOKIE_TIME']= "604800";
$settings['COOKIE_PATH']= "/";
$settings['COOKIE_DOMAIN']= ".";


$settings['SKIN']= "starling";
?>
