Php Magento:购物车页面和签出页面为空错误

我对magento 1.9.0.1有疑问

我在签出页面上遇到了这个错误，我尝试了很多来自谷歌的解决方案，但不适合我，所以请你提出一些好主意

Invalid method Mage_Page_Block_Html::addItemRender(Array
(
    [0] => bundle
    [1] => bundle/checkout_cart_item_renderer
    [2] => checkout/onepage/review/item.phtml
)
)

我的购物车页面上也有一个错误，它只是显示为空。我已经用模板提示进行了测试，它只是像下面这样显示

frontend/base/default/template/catalog/msrp/popup.phtml

---

我已经解决了我的问题。我刚刚备份了当前主题的checkout模板文件夹和checkout.xml，并从基础上复制了checkout文件夹和checkout.xml，这对我很有用

这是我的主题问题。我已经发布了购物者主题。布局文件夹中没有任何签出的xml
