Hi everybody ,i'm newbie in this forum and also in codeigniter framework, sorry if my ask is stupid, but, to day i create my first page with the last version CodeIgniter_1.5.4, but when access to scaffolding for my table "typeplayer" to url:

http://localhost/soccer/index.php/player/scaffolding

The page is ok, but to try add a record to my table, the links create is the same url more index.php/player/scaffolding/add

http://localhost/soccer/index.php/player...olding/add

and throws error: 404 Page Not Found

but I try with http://localhost/soccer/index.php/player...olding/add

I see the form to my table but the error continue with the others actions.

My class here:

parent :: Controller();
$this->load->scaffolding('typeplayer');
}
}
