Loading page gives an error in CodeIgniter

When I login, it gives me "error page not found". It's not loading the controller function.

This is my view file:

<form name="loginform" action="welcome/login" method="post">
Enter User Name:
<input type="text" name="uname">
Enter Password
<input type="password" name="pass">
<input type="submit" name="login" value="Login">

This is my login controller file:

class Login extends Controller {
    function Login()
    {
        parent::Controller();   
    }
    function login()
    {
        $this->load->view('welcome_message');
    }
}

This is my welcome controller file:

class Welcome extends Controller {

    function Welcome()
    {
        parent::Controller();   
    }
    function index()
    {
        $this->load->model('Loginmodel');
        $this->load->view('welcome_message');
    }
    public function login()
    {
        $this->load->model('Loginmodel','login');
        $info = $this->logn->login();
        $this->load->view('welcome_message',$info);
    }
}

Can you give me any idea what is wrong?

The code you provided seems fine, so I would guess it has to do with this:

<form name="loginform" action="welcome/login" method="post">

The path is relative, which is only going to work if there are no url segments present. If the current URL is /hello/world, you will end up posting to /hello/world/welcome/login

Try a full URL or absolute path. Example:

<form name="loginform" action="/welcome/login" method="post">
                         <!-- ^^^ Note the leading forward slash -->

Or use base_url() for the full url:

<form action="<?php echo base_url(); ?>welcome/login">

You may also be interested in the form_open() function which will do this automatically.

<?php echo form_open('welcome/login'); ?>

The only other thing I can see would have to do with whatever $this->login->login(); does. If you can confirm what your URL actually is when you see the "page not found" error, that would be a great help.
