Same page refreshes upon Authentication, laravel 5.1

I am using laravel 5.1 framework on windows. I installed xampp, and created a database. And the following command created two tables in the database: users and password_reset

php artisan migrate

now I followed every step mentioned in the laravel doc for authentication, but problem is everytime I click register it refreshes the page, without redirecting the page mentioned in authcontroller ( in my case, protected $redirectPath = '/'; )

I checked the database, no changes were made.

So what went wrong???
