我试着去http://localhost/Symfony/web/config，然后我点击“配置你的 symfony 应用程序”，然后我收到以下错误：
No data received
Unable to load the webpage because the server sent no data.

Reload this webpage later.
Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.
知道我应该调试什么以及如何调试吗？我正在 OS X Mountain Lion、apache2 和 PHP 5.4.6 上对此进行测试
在我的日志中，我看到以下内容：
