Hi Guys,

I am new to magento. My client recently shifted his project from one server to another. When we take the front-end it was showing the error “Invalid backend model specified: catalog/attribute_backend_customlayoutupdate” , but I have fixed it based on the suggestions given here. But currently it is showing a new error as given below


Invalid backend model specified: catalog/product_attribute_backend_sku

Hi All,

I have solved this issue. Sku.php file was missing in app\code\core\Mage\Catalog\Model\Product\Attribute\Backend\ folder.

When I placed this file in this location the site became live and now its working fine.

Im putting this bcoz somebody else may find it useful.

Enjoy!!!!!!!!!
