我正在尝试将Joomla网站从一个托管转移到另一个托管。 错误是：
Fatal error: Call to a member function get() on a non-object in /home/.../templates/beez_20/error.php on line 10
我在error.php中找到了以下行：
defined('_JEXEC') or die;
$params = JFactory::getApplication()->getTemplate(true)->params;
$logo = $params->get('logo');
也许它无法找到参数，所以我应该将其初始化？
在致命错误之前还有几个警告：
