I have a website built on ASP.NET MVC4, .NET 4.0
It is deployed on a server running IIS7. I have done minor changes
Added AutoMapper (using nuget package) and used it in one of controllers
Added a new controller derived from ApiController (other ones were derived from Controller)
The site works well on my dev machine (both Cassini and IIS).
When I released the new version to the server, it did not work and showed the error page (below). I am not sure what is the cause and how to fix it. Could you help me, please?
UPDATE 1
Version with ApiController but without AutoMapper works well.
Server Error in '/' Application.
