有些時候DNN中程序出錯的提示沒有指出具體的出錯位置，如果使用斷點跟蹤也不知在何處插入斷點，這樣我們debug完全只能靠猜測，比如如下的出錯提示：
Error: Edit Content is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException:

使用這個文件就可清楚的看到是哪裡出了問題：
下載 DNNDebug.rar 文件並解壓得到 "DNNDebug.aspx" 文件
把這個文件放在DotNetNuke網站的根目錄裡
然後在浏覽器裡訪問這個文件 (如: http://localhost/Dotnetnuke/DNNDebug.aspx)
輸入加載時出錯的web contol地址(比如: ~/DesktopModules/Feedback/Feedback.ascx)
如果幫你解決的大問題，你可以給作者Nik 發個郵件表示感謝
注意！
網站發布時一定要刪除這個文件！！
