Magento issue after updating from 1.4 to 1.5

Question

I have upgraded my Magento version 1.4.2.0 to 1.5.0.1. Every thing is ok, but after clicking on wishlist I get the following error. Can anyone tell me what's the problem?

Invalid method Mage_Wishlist_Model_Item::canConfigure(Array
(
)
)

Answer 1

It is caused by sidebar.phtml in app\design\frontend\default\\template\wishlist.

Please compare to sidebar.phtml in base theme. I'm upgrade our magento themes to 1.5.0.1

Answer 2

I had a similar problem when upgrading with deleted block-methods being called form the layout xml files. I removed the lines in the XML configuration that was troubling (top.links rendering would fail)

Answer 3

It is likely that your magik_computerstore theme was coded for 1.4 and has not been adjusted for 1.5. If it makes calls that are no longer appropriate, errors like this can occur. I would suggest checking with your theme developer for 1.5 compatibility.

Answer 4

As has been mentioned, it's your custom theme. Your app\design\frontend\default\template\wishlist.phtml file is calling $this->getPriceHtml() and passing a wishlist item when it expects a product.

Example:

$this->getPriceHtml($_item);

When it expects:

$this->getPriceHtml($_item->getProduct());

But you are assured to have more errors if the theme was written for and older version of Magento.
