我刪除並重新創建了ASP.Net網站的子域。然後我上傳了這些文件，但是當我去打開一個瀏覽器時，我得到一個安全異常，指出我必須修改應用程序的配置文件以授予信任。不幸的是，錯誤信息並沒有說明導致問題的文件，是一個問題的信任，或者我能看到的任何東西。ASP.Net在實際網站上產生安全異常
這是我所看到的：
Server Error in '/' Application.

的思考？
您是否在中等信任基礎上運行？ – SLaks
我認爲我是中等信任的。我處於共享主機環境，所以無論如何都是合理的。我認爲我記得從以前與網絡主機提供商的通信中得知，這是真的。有趣的是，該網站曾經很好地工作。電腦上週墜毀，他們主持了我的帳戶。他們重建了一些東西，但是使用了舊版本的備份，無論如何。我決定最簡單的方法是刪除子域，重新創建子域，然後再次上傳文件。但是，該行爲仍產生相同的錯誤消息。 –
我知道我不允許在共享主機環境中「完全信任」，並且網站工作正常。當Web主機提供商重新構建機器時，他們可能會改變信任級別，並使其比ASP.Net/DevExpress喜歡的更具限制性。我不知道哪個組件實際上導致失敗。堆棧跟蹤我不清楚。 –
