'/'应用程序中的服务器错误。在ASP.NET Web应用程序中

Question

我已使用Visual Studio将我的ASP.NET Web应用程序上传到我的Web主机。以下是Visual Studio的输出：

2>Copying all files to temporary location below for package/publish:
2>obj\Release\Package\PackageTmp.
2>Publishing folder /...
2>Publishing folder Account...
2>Publishing folder bin...
2>Publishing folder Examples...
2>Publishing folder Examples/Example 1...
2>Publishing folder images...
2>Publishing folder jQuery.easySlides...
2>Publishing folder jQuery.easySlides/css...
2>Publishing folder jQuery.easySlides/img...
2>Publishing folder jQuery.easySlides/js...
2>Publishing folder Scripts...
2>Publishing folder Styles...
2>Publishing folder UserControls...
2>Publishing folder YouTube...
2>Site was published successfully http://blahblah.cp.blacknight.com/
2>Site was published successfully http://www.mywebsite.com/

我已经使用FileZilla检查过我的所有文件都在上传的位置，而且它们都是。

当我浏览我的网站时，我收到以下错误：

这是我的Web.config页面：
