Question

我无法达到网站设置。我只是收到此错误消息：PageLoadException：对象引用未设置为对象的实例和a：System.ComponentModel.Win32Exception（0x80004005）：等待操作超时

我真的对此错误感到困惑并且已经搜索了修复程序，但没有找到解决方案。

有谁知道如何解决它？ 或者有任何想法如何？这是数据库中的堆栈跟踪：

我想我已经遇到过这个错误。这可能是由于门户网站目录中的文件夹数量过多以及用户数量很大我发现的一个解决方案是修改存储过程我建议你验证“GetFoldersByPermissions”的代码我的更改包括评论似乎不需要的2个连接：
JOIN dbo.UserRoles UR ON UR.RoleID = FP.RoleID
加入dbo.Users U ON U.UserId = UR.UserId

Dotnetnuke站点设置PageLoadException：对象引用未设置为对象的实例
