Routes file doesn't work

I will give you my files first, and after that I will explain my problem:

application/config/routes.php file: https://pastebin.com/jbBeqmEs
application/controllers/Users.php file: https://pastebin.com/6KwPn5Cq
application/view/users/registration.php file: https://pastebin.com/ZrY8nhxu

When I try to enter my beta domain, which is

Code:

http://drpciv.mauriceltd.co.uk/registration

I recieve 

404
Not Found
The resource requested could not be found on this server!

But I declared the route in the route.php file.. I read everything about routing from documentation but still I don't have any ideea why this doesn't work.
