Application Exception
Runtime Error
A runtime error has occurred

描述：服务器上出现应用程序错误。此应用程序的当前自定义错误设置会阻止查看应用程序错误的详细信息（出于安全原因）。

详细信息：要查看此特定错误消息的详细信息，请在位于当前 Web 应用程序根目录的“web.config”配置文件中创建一个标签。然后，此标记应将其“模式”属性设置为“关闭”。

 <!-- Web.Config Configuration File -->

    <configuration>
        <system.web>
            <customErrors mode="Off"/>
        </system.web>
    </configuration>    

注意：您看到的当前错误页面可以通过修改应用程序配置标签的“defaultRedirect”属性以指向自定义错误页面 URL 来替换为自定义错误页面。

    <!-- Web.Config Configuration File -->    
    <configuration>    
        <system.web>    
            <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>    
        </system.web>    
    </configuration>

使用 Google 快速搜索显示：

CustomErrors mode="Off"

基本上你需要调整一些其他的设置
