Answer 1

Here is latest and quick fix for showing custom 404_error page.

• Add below lines in development.rb or production.rb as per your env.

config.exceptions_app = self.routes

config.consider_all_requests_local = false

• Remove all rm public/{404,500,422}.html
• Create 404.html.erb file in static folder of your rails project. You can add your custom html here.(this will be using your application layout so don't bother about header and footer content)
