以下问题是DotNetNuke相关 - 但在我看来是一个与asp.net相关的错误，我真的很感激每一个提示来解决这个问题。
我遇到以下问题：在我的开发环境（Win 8.1，SqlServer 2008 R2 express，VS2013）中全新安装DotNetNuke 7.4.2后编辑Html模块的内容时，最后显示的异常会引发。在测试环境中安装7.4.2（Win 2K8服务器64位，SqlServer 2008 R2 express）时，编辑模块没有错误，一切正常。
使用空数据库完成安装，修改web.config以指向此数据库并调用http://dnndev.me/install/install.aspx。该网站具有自己的应用程序池，并且应用程序池用户已被授予安装文件夹的必要权限。顺便说一句：从DNN v4开始，这个程序已成功使用（有修改）。
谷歌搜索没有显示太多结果。我试过的是清除“v4.0.30319 \ Temporary ASP.NET Files”文件夹 - 没有成功。
有没有人知道这个错误的原因是什么？
感谢您的想法， 罗伯特
val lst = List(1,2,3,4)
val records = sc.parallelize(lst).zipWithIndex.filter(_._2 > 0).map(_._1)
val records.collect() // Array[Int] = Array(2, 3, 4)

网站dnndev.me（及其应用程序）之前已用于其他安装。
删除并重新创建网站（暗示应用程序）解决了错误（请注意，创建新的应用程序池是不够的。）
如果有解释，我会非常感激。
编辑：将当前的applicationHost.config与旧版本进行比较显示了错误的原因：还有一个附加条目指向其他旧版本中路径的完全限定名称。这导致了使用两个版本的编译（这是Panagiotis已经写过的）。

如果您已经删除了该网站，那么检查可能为时已晚，但我会检查该网站下是否有DesktopModules上的Application / VirtualDirectory或其中的任何子文件夹。这是我在Visual Studio中的模板的常见问题，由于某种原因，随机，VS会将这些文件夹转换为单个应用程序，这会导致各种混乱，直到您在IIS中删除该应用程序。
