Asp.net mvc 4 500错误代码内部服务器错误

我最近在一个webhost服务器上托管了一个asp.net mvc4网站，在部署之前，一切正常，包括远程数据库连接，但在将发布的文件移动到托管服务器后，我无法远程浏览该网站。我收到一个500-内部服务器错误（您正在查找的资源有问题，无法显示）。我已查看了web.config文件，但找不到任何内容。联系我的主机提供商后，我被要求添加

     <modules runAllManagedModulesForAllRequests="true"/>,

，

我这样做了，但仍然得到相同的错误。伙计们，我需要你们的帮助，谢谢

将此项设置为on，您将看到显示的实际错误，以便调试错误@danm谢谢你的建议……实际上我必须重新发布这个应用程序，现在它工作正常了
