Magento 1.3.3 error at showing checkout shoppin cart

As soon as I try to add a product to the shopping cart in Magento, it spits this PHP error:

Fatal error: Call to undefined method Mage_Catalog_Model_Resource_Eav_Mysql4_Product_Collection::addTierPriceData()

I don't know what is it about; I've tried the Magento forum and I haven't yet found out a solution to this.

I installed magento through SimpleScripts.com, in a hostmonster.com account. My stor开发者_如何学Goe is still waiting to launch due to this strange error(www.caninarua.com/shop). I really don't know what to do now...please help.

Thanks.

There's nothing in the default v1.3.2.4 Magento codebase that calls addTierPriceData() on that class. It does, however, exist in v1.4.2 and is called by Mage_Bundle_Model_Product_Price::getFinalPrice()

So, either you have a commercial theme that is calling that function (unlikely), or an extension that has been installed that is not compatible with v1.3.3

If you turn on logging in System>Config>Admin>Developer, you should get a full stack trace in var\log\exception.log which you can paste into your question and we can verify which piece of code is calling that method.
