The constant OPTION_PREFIX
is declared as a constant on the Mage_Catalog_Model_Product_Type_Abstract
class in CE 1.7 and newer. Based on the results of searching with ack OPTION_PREFIX
on the CLI, the term does not exist nor is referenced in older versions of Magento.
Would I be correct to surmise that your installation used to be running an older version of Magento and has been upgraded to CE 1.7?
My suggestion would be to verify that the constant is declareddefined in the class Mage_Catalog_Model_Product_Type_Abstract
declaration found in app/code/core/Mage/Catalog/Model/Product/Type/Abstract.php
. Assuming it is, I would go looking for a copy of that class that is overriding the core file, like say, a file in the local code pool which overrides the core class declaration with a copy of the class from an older version of Magento.
