title: Laravel application show blank page without error and log
body: <p>I updated the project but it turn out showing blank page for all frontend route, I roll back the changes but seems no luck.</p>
  
  <p>The backend works:
  <a href="http://unionmaterials.com.hk/admin" rel="nofollow noreferrer">http://unionmaterials.com.hk/admin</a></p>
  
  <p>The frontend, however, every page just return blank page</p>
  
  <p><a href="http://unionmaterials.com.hk" rel="nofollow noreferrer">http://unionmaterials.com.hk</a></p>
  
  <p><a href="http://unionmaterials.com.hk/page/contact" rel="nofollow noreferrer">http://unionmaterials.com.hk/page/contact</a></p>
  
  <p>I have tried log in the controller and </p>
  
  <pre><code>class PageController extends Controller
  {
      /**
       * Create a new controller instance.
       *
       * @return void
       */
      public function __construct()
      {
  
      }
  
      /**
       * Show the application dashboard.
       *
       * @return \Illuminate\Http\Response
       */
      public function contact()
      {
          $this-&gt;data['contact'] = Contact::find(1);
          return view('contact')-&gt;with($this-&gt;data);
      }
  }
  </code></pre>
  
  <p>If I change to another view, e.g. <code>return view('welcome')-&gt;with($this-&gt;data);</code>, it works, so I copy the whole content from welcome to contact, but it still return blank page</p>
  
  <p>Anyway to fix the problem ? 
  Thanks a lot</p>
