找不到CodeIgniter和Nginx-Class

我已经使用Apache将CodeIgniter应用程序从本地主机上传到运行Nginx的服务器。

它在我的本地主机和其他使用Apache的服务器上都能很好地工作。

它在一个子域下，一个域和其他子域都在100%运行PHP。

CI中的这个应用程序没有启动，PHP在没有编译的情况下返回。

这是我在/var/log/nginx/error.log上看到的内容：

2013/12/05 14:50:31 [error] 20139#0: *1 FastCGI sent in stderr: "PHP message: PHP Fatal error:  Class 'M_website' not found in /home/webroot/domain.com/cms/system/core/Loader.php on line 303" while reading upstream, client: 84.91.4.220, server: cms.domain.com, request: "GET /websites HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "cms.domain.com"

在/home/webroot/domain.com/cms/system/core/Loader.php中找不到类'M_website'

这是我的子域配置。

    server_name cms.domain.com;

    }

    if ($host ~* ^www'.(.*))
    {

    }
    # removes trailing "index" from all controllers

    }

        break;
    }
