如何在Laravel上解决ErrorException

问题描述 投票：0回答：1

我已经将Laravel应用程序从一台服务器迁移到另一台服务器，但是在新服务器上，它抛出了如下错误：注意：它位于共享主机上。

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)

下面是我的观点：

<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">

      <div class="navbar nav_title" style="border: 0;">
        <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>
