Laravel 5 authentication weird behaviour - laravel

Question

Before explaining the problem. Let me explain, things i have tried out.I ran the command
php artisan make:auth
it created files like HomeController, a directory auth which had register & login pages. in my application i have a directory Pages. i opened up AuthenticatesUsers trait and changed
return view('auth.login'); to my view return view('Pages.login');
After that: i changed view of showRegistrationForm methods view return view('auth.register'); to return view('Pages.register'); from RegistersUsers.php
Here is UserController
lass UserController extends Controller {
//constructor
public function __construct() {
}
//Admin: return view
public function showCommunity() {
$Community = Community::latest()->get();
$Ideas = Idea::latest()->get();
return view('privatePages.communities', compact(array('Community', 'Ideas')));
}
Routes that were generated by php artisan make:auth
Route::auth();
//Auth Controller
Route::controllers([
'auth' => 'Auth\AuthController',
'password' => 'Auth\PasswordController',
]);
Now coming back to the problem. yesterday morning. When i opened up localhost/auth/register. Registration process was working fine and data was storing in DB. But there was an issue with login view. Neither it was throwing an error on wrong credentials nor logged the user in on correct credentials. Later in the evening. Login view was working and throwing an error even upon entering correct credentials it said Credentials does not match record. But registration process was not working and data was not storing in DB. It really confusing.
Here is AutheticatesUsers File

One more thing for registration process. I am not using laravel's Request rather my own created 'UserRequest`. If any other information is needed. i would provide that. Any help would be appreciated.
