Symfony 错误：RuntimeException 您的配置必须至少有一个域

当我尝试访问我网站上的网页时，出现以下错误日志：

(1/1) RuntimeException 您的配置必须至少有一个域。

这是 app_dev.php 文件：

<?php

use Symfony\Component\Debug\Debug;
use Symfony\Component\HttpFoundation\Request;

// If you don't want to setup permissions the proper way, just uncomment the following PHP line
// read https://symfony.com/doc/current/setup.html#checking-symfony-application-configuration-and-setup
// for more information
//umask(0000);

// This check prevents access to debug front controllers that are deployed by accident to production servers.
// Feel free to remove this, extend it, or make something more sophisticated.
if (isset($_SERVER['HTTP_CLIENT_IP'])
    || isset($_SERVER['HTTP_X_FORWARDED_FOR'])
    || !(in_array(@$_SERVER['REMOTE_ADDR'], ['1xx.0.0.1','1xx.0.16.163','1xx.0.0.250','1xx.0.0.226','1xx.0.0.233','::1'], true) || PHP_SAPI === 'cli-server')
) {
    header('HTTP/1.0 403 Forbidden');
    exit('You are not allowed to access this file. Check '.basename(__FILE__).' for more information.');
}

require __DIR__.'/../vendor/autoload.php';
Debug::enable();

$kernel = new AppKernel('dev', true);
if (PHP_VERSION_ID < 70000) {
    $kernel->loadClassCache();
}
$request = Request::createFromGlobals();
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);

这是这个项目的第一个bundle，我也检查过路径是否正确，没问题。配置文件看起来很棒，ISPConfig 也是。我不知道去哪里找。

谢谢 ！
