title: Basic route with paramter failing in Laravel 5.3
body: <p>I have a basically fresh install of Laravel 5.3 and I wanted to look into passing parameters to a route. I literally copied this from Laravel Docs,,</p>
  
  <pre><code>Route::get('user/{id}', function ($id) {
      return 'User '.$id;
  });
  </code></pre>
  
  <p>When I try to access the route:</p>
  
  <pre><code>http://testsite.dev/user/1
  </code></pre>
  
  <p>I should see </p>
  
  <pre><code>User 1
  </code></pre>
  
  <p>Instead I get this:</p>
  
  <pre><code>Sorry, the page you are looking for could not be found.

  <p>This does not happen with routes without parameters.</p>
