如何解决 Laravel 上的 ErrorException

Question

我已经将 Laravel 应用程序从一台服务器迁移到另一台服务器，但在新服务器上它会抛出如下错误：注意：它在共享主机上。

ErrorException in dad68dc02a27f7285385d1802abef8de21c58892.php line 126: Trying to get property 'designer' of non-object (View: /home/username/orders.example.com/appz/resources/views/layouts/gentella.blade.php) (View: /home/username/orders.example.com/appz/resources/views/layouts/gentella.blade.php)

以下是我的看法：

<div class="container body" style="width: 100% !important;padding: 0px !important;">


<div class="main_container">

  <div class="col-md-3 left_col">
    <div class="left_col scroll-view">

        <a href="{{ URL::to($navbar_menu->url) }}" class="site_title"><i class="fa fa-paw"></i> <span>{{ $navbar_menu->label }}</span></a>
      </div>
      <div class="clearfix"></div>
