Routes problem

Please show the exact 404 message including "some controller that I don't have."

Just a guess, but I suspect you have not used namespace correctly.

So if i try to access that route with:
korisnik/admin/urediFeed/22
I get this:

Controller or its method is not found: \App\Controllers\Pers::index

It should not be namespace, because when I remove (:num) and $1, that route opens file from view which should be opened before  with (:num) and $1 in route definition.

EDIT:

I decided to test this route with this:
I added (:num) in URI part and removede $1 from "right side" parameter, and it worked. But as soon as I add .... 'Pers/UserAdministracija::urediFeed/$1', it stop working. So am I passing $1 in correct way to my method "urediFeed" or what?
