The URI you submitted has disallowed characters?

Thank you for the link. I don't think I understand how to properly use the routes

if I want my link to be mydomain.com/verify/EMAIL/HASH

I added this route: $route['verify/(:any)/(:any)'] = "verify/";

But I still get the 404, what part did I misunderstand?

I also tried: $route['verify/(:any)'] = "verify/"; and $route['verify/(:any)'] = "verify";
