When accessing a link to a post that has been removed from my mobile, instead of getting a nice removed page, I receive a "server error in '/' Application." error page from IIs.

If accessed from a desktop browser I receive a simple error message "The page you requested was removed.", however, a mobile browser receives the error message.
