Server Error in '/' Application. Cannot use a leading .. to exit above the top directory

Question

I am trying to develop a C# web-based system with multiple user roles. Created in my project is sub-folders for Human Resources (HR), Finance and Contractors. In addition I am inheriting from the MaterPage which is in the root folder. This uses siteMaps. However, I am encountering this error when I try to access the folders. I have looked at the other examples and changed my code to use ~/ but still having the same error. Any help would be appreciated. Thanks.

Answer 1

The positioning of the Bootstrap in the Master was wrong. I removed this and it worked by just placing it further down the CSS.
