C# 联机加载页面时web.config文件出错

错误 服务器上发生应用程序错误。此应用程序的当前自定义错误设置阻止远程查看应用程序错误的详细信息（出于安全原因）。但是，本地服务器上运行的浏览器可以查看它

我的web.config就在这里

您用什么来主持项目？您是否已检查主机上是否安装了正确的.NET版本？您是否能够访问远程服务器（并使用远程计算机的浏览器查找问题）？您可以尝试启用IIS错误，并找出应用程序池中使用的确切消息和.NET版本。我使用的是Cpanel，是的，我可以访问Cpanel IIS设置。这与IIS错误或AppPool不同。我的.NET版本为4.6，不知道在哪里可以看到主机的.NET版本
