Relative virtual path ‘AspNetForumMaster.Mobile.Master’ is not allowed here

Problem:

On mobile devices, the following error occurs:

The relative virtual path ‘AspNetForumMaster.Mobile.Master’ is not allowed here.

I do note that the file mentioned doesn’t exist at all in the directory structure.


Solution:

Please remove all the files except web.config, download the application files all over, and reinstall the application.
