Authentication and code, email confirmation Laravel 5.1

I'm a bit frustrated over logging in using this code. I followed this tutorial - Laravel authentication, logging in.

This is my register page:

@extends('layouts.master')

    @section('title')
        Create User
    @stop

    <link href="{!! asset('css/style.css') !!}" media="all" rel="stylesheet" type="text/css" />

    @section('body')
        {!! Form::open(array('action' => 'UserController@store')) !!}

            @if (count($errors) > 0)
                <div class="alert alert-danger">
                    <ul>
                        @foreach ($errors->all() as $error)
                            <li>{{ $error }}</li>
                        @endforeach
                    </ul>
                </div>
            @endif
            <DIV align="center"><SPAN class="div-header">MEMBER REGISTRATION</SPAN></DIV>
            <TABLE>
                <TH>FIELDS</TH><TH>DESCRIPTIONS</TH>

            </TABLE>
        {!! Form::close() !!}
    @stop

The routes:

Route::resource('users', 'UserController');

Route::get('auth/login/{confirmationCode}', ['as' => 'verifypage', 'uses' => 'UserController@confirm']);

Route::get('auth/login', 'Auth\AuthController@getLogin');
Route::post('auth/login', 'Auth\AuthController@postLogin');
Route::get('auth/logout', 'Auth\AuthController@getLogout');

// Registration routes...
Route::get('auth/register', 'Auth\AuthController@getRegister');
Route::post('auth/register', 'Auth\AuthController@postRegister');

The controller:

public function loginUser()
    {
        $rules = [
            //'username' => 'required|exists:users',
            'email' => 'required|exists:users',
            'password' => 'required'
        ];

        $input = Input::only('username', 'email', 'password');

        $validator = Validator::make($input, $rules);

        if($validator->fails())
        {
            return Redirect::back()->withInput()->withErrors($validator);
        }

        $credentials = [
           // 'username' => Input::get('username'),
            'email' => Input::get('email'),
            'password' => Input::get('password'),
            'confirmed' => 1
        ];

        if ( ! Auth::attempt($credentials))
        {
            return Redirect::back()
                ->withInput()
                ->withErrors([
                    'credentials' => 'We were unable to sign you in.'
                ]);
        }

        Flash::message('Welcome back!');

        //return Redirect::index();
        return view('userpages.index');
    }

This code executed but only keeps giving routing problems. I'm surprised it can't find the index page or I'm doing something wrong. It executed because i can see in the db the value of confirmed column changed to 1 in the db. What exactly I'm i doing wrong. I appreciate your valid input. Please , exact code snippet will be appreciated. m getting]2]2
