Authentication failed results in WSOD - laravel

Question

I'm using Larave 4.2, and everything works just fine. If I enter the correct credentials I will be taken to the correct URL (the one with auth filter). But the problem I'm currently experiencing is when one of the fields entered is incorrect and the user submits it will show a white screen.
I'm expecting of course that the user will be redirected back to login page with Input and display the error.
I've checked the filters, and quite sure it is still what came with Laravel and didn't change anything.
My routes
<?php
Route::get('login', function()
{
// just a shortcut to redirec to /login into /cms/login : prevents redirect LOOP
return Redirect::route('cms.login');
});
Route::group(array('prefix' => 'cms'), function()
{
Route::get('/', function()
{
if (Auth::guest())
{
return Redirect::route('cms.login');
}
else
{
return Redirect::route('cms.home');
}
});
Route::get('login', array(
'as' => 'cms.login',
'uses' => 'CMSController#login'
));
Route::post('login', array(
'as' => 'cms.postLogin',
'uses' => 'CMSController#userLogin'

Route::get('logout', array(
'as' => 'cms.logout',

Currently in your code there is nothing after Auth::attempt() - so if the Auth fails - it has no where to go.
Just add a return after the Auth::attempt() to make it work
if (Auth::attempt(array(
'email' => $user_credentials['email'],
'password' => $user_credentials['password']), $remember_me))
{
return Redirect::route('cms.home');
}
return Redirect::route('cms.login')->withInput()->withErrors($errors);
