    $this->loadComponent('Auth', [
        'authorize' => ['Controller'],
        'authenticate' => [
            'Form' => [
                'fields' => [
                    'username' => 'email',
                    'password' => 'password'
                ],

            ]
        ],
        'loginAction' => [
            'controller' => 'Users',
            'action' => 'login'
        ],
        'unauthorizedRedirect' => $this->referer(),
        'logoutRedirect'       => [
                'controller' => 'Users',
                'action'     => 'login'
        ]
    ]);
}

In loginController.php

function login{ 
 if ( $this->request->is( 'post' ) ) {
    if ( $this->Auth->login() ) 
    {
       $this->redirect($this->referer());
    } 
    else {
      $this->Flash->error(__('Your username or password is incorrect.'));
    }
  }
}

Answer 1

Looks like you got some redirect loop here. You should use AuthComponent::redirectUrl().

public function login()
{
    if ($this->request->is('post')) {
        $user = $this->Auth->identify();

        if ($user) {
            $this->Auth->setUser($user);
            return $this->redirect($this->Auth->redirectUrl());
        } else {
            $this->Flash->error(__('Username or password is incorrect'));
        }
    }
}

See the Redirecting Users After Login in the Documentation.

After logging a user in, you’ll generally want to redirect them back to where they came from. Pass a URL in to set the destination a user should be redirected to after logging in.

If no parameter is passed, the returned URL will use the following rules:

• Returns the normalized URL from the redirect query string value if it is present and for the same domain the current app is running on. Before 3.4.0, the Auth.redirect session value was used.
• If there is no query string/session value and there is a config loginRedirect, the loginRedirect value is returned.
• If there is no redirect value and no loginRedirect, / is returned.

Answer 2

Use $this->Auth->redirectUrl() instead of $this->referer().

After logging a user in, you’ll generally want to redirect them back to where they came from. Pass a URL in to set the destination a user should be redirected to after logging in.

• Returns the normalized URL from the redirect query string value if it is present and for the same domain the current app is running on. Before 3.4.0, the Auth.redirect session value was used.
• If there is no query string/session value and there is a config loginRedirect, the loginRedirect value is returned.
• If there is no redirect value and no loginRedirect, / is returned.

Add to your AuthComponent configuration options:

loginRedirect

The URL (defined as a string or array) to the controller action users should be redirected to after logging in. This value will be ignored if the user has an Auth.redirect value in their session.

Your code should be like that:

In appController.php

public function initialize()
{ 
    parent::initialize();
    $this->loadComponent('RequestHandler');
    $this->loadComponent('Flash');
    $this->loadComponent('Auth', [
        'authorize' => ['Controller'],
        'authenticate' => [
            'Form' => [
                'fields' => [
                    'username' => 'email',
                    'password' => 'password'
                ],
                'scope' => ['userStatus' => '1']
            ]
        ],
        'loginAction' => [
            'controller' => 'Users',
            'action' => 'login'
        ],
        'unauthorizedRedirect' => $this->referer(),
        'logoutRedirect'       => [
                'controller' => 'Users',
                'action'     => 'login'
        ],
        'loginRedirect' => [
            'controller' => 'Pages',
            'action' => 'display'     
        ]
    ]);
}

In loginController.php

function login{ 
 if ( $this->request->is( 'post' ) ) {
    if ( $this->Auth->login() ) 
    {
       $this->redirect($this->Auth->redirectUrl());
    } 
    else {
      $this->Flash->error(__('Your username or password is incorrect.'));
    }
  }
}
