Laravel 5 Form Request Blank Screen Error on DigitalOcean - laravel-5

Question

I'm creating a contact form in Laravel 5. The contact form is on homepage and when a user fills it out then clicks the submit button, laravel sends the email using mandrill and just refreshes the page. The code works perfectly on my Local environment. However on digital ocean droplet when a user clicks the submit button, domain.com/contact route is being triggered and I can only see a blank page.
Here is my controller
<?php namespace App\Http\Controllers;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\Http\Requests\ContactFormRequest;
use Illuminate\Http\Request;
class ContactController extends Controller {
public function create() {
return view('forms.contact');
}
public function store(ContactFormRequest $request) {
\Mail::send('emails.contact',
array(
'name' => $request->get('name'),
'email' => $request->get('email'),
'user_message' => $request->get('message')
), function($message)
{
$message->from('info#pbl-landing.com');
$message->to('muhammetergenc#gmail.com', 'Admin')->subject('Contact Request');
});
return \Redirect::route('index')->with('message', 'Thanks for contacting us!');
}
}
Here is my routes.php file
Route::get('/',
['as'=>'index', 'uses'=>'WelcomeController#index']);
Route::get('home', 'HomeController#index');
Route::controllers([
'auth' => 'Auth\AuthController',
'password' => 'Auth\PasswordController',
]);
Route::get('contact',
['as' => 'contact', 'uses' => 'ContactController#create']);
Route::post('contact',
['as' => 'contact_store', 'uses' => 'ContactController#store']);
