上傳多城市部署在【阿里云虛擬主機基礎班】中報錯

我看阿里云【阿里云虛擬主機-基礎班】的域名綁定，最多能綁定1000個。


多城市上傳上去【報：運行時錯誤】

“/”應用程序中的服務器錯誤。
運行時錯誤
說明: An exception occurred while processing your request. Additionally, another exception occurred while executing the custom error page for the first exception. The request has been terminated.


環境已設置.net FrameWork版本:V4.0/V4.5(經典)，請老大告知一下要設置下哪個代碼才能完美適配。
