我只是想克隆moneybookers支付模块到Open Cart中的mpower支付模块，然后猜测我现在被困在这里的错误是：
Fatal error: Call to undefined method Loader::controller() in /home/hunter/public_html/opencart_new/admin/controller/payment/mpower.php on line 213

行号213为：
$data['header'] = $this->load->controller('common/header');
我还没有完全完成模块的开发，但几乎完成了支付模块的管理端，但它出现了错误，所以如果有人能看一看，让我知道我做错了什么，请？
这是第213行之后的代码：
替换此代码：
$data['header'] = $this->load->controller('common/header');
$data['column_left'] = $this->load->controller('common/column_left');
$data['footer'] = $this->load->controller('common/footer');
$this->response->setOutput($this->load->view('payment/mpower.tpl', $data));
带
$this->template = 'payment/mpower.tpl';
$this->children = array(
'common/header',
'common/column_left',
'common/footer'
);
$this->response->setOutput($this->render());
无需为页眉、页脚等调用控制器。
而且不需要在setOutput中传递$data，当你在浏览器中加载支付网关链接时，它会自动传递到你的视图文件中，因为默认情况下它会调用你的索引方法。
我遇到了同样的问题，发现我在opencart版本1.5.X.X中使用了2.0.X.X模块。您可能只是使用了错误版本的模块。
