Параметр маршрутизации Larevel 4.2% 7Busername% 7D не работает

Я делаю небольшой проект, используя laravel, но маршрутизация не работает по какой-то причине, пожалуйста, укажите мне в правильном направлении, ниже я отправляю код.

маршрутизатор

Route::get('{username}', array('as' => 'profile', 'uses' => 'ProfileController@index'));

контроллер

  public function index($username = null) {
        $username = Sentry::getUser()->username;

        return View::make('home.profile')
                 ->with('title', 'From controller')
->with('username', $username);

    }

Url http://social.app/%7Busername%7D

public function postLogin(){
        $credentials = Validator::make([
                    'email' => Input::get('email'),
                    'password' => Input::get('password')
                        ], [
                    'email' => 'required|email',
                    'password' => 'required|alpha_num|between:8,15',
        ]);
        if ($credentials->fails()) {
            return Redirect::route('login')
                            ->withInput()
                            ->with('title', 'Welcome to mySite | login')
                            ->withErrors($credentials->getMessageBag());
        } else {
            try {
