I was stupid. upgrade the google shopping ..
now my version is 18.104.22.168, and I connected magento connect and try to upgrade the new “Google Content API for Shopping”
then the result is
whenever I change anything in manage product , it failed and the words is “
Fatal error: Class ‘Mage_Core_Model_Resource_Db_Collection_Abstract’ not found in /***/***/***/app/code/core/Mage/GoogleShopping/Model/Resource/Item/Collection.php on line 34
it seems google shopping thought I was make some change to the products, so they need collect it and update to the google shopping?
So I try to disable it, uninstall it, and never success.
why? how? I can’t uninstall google shopping. because it’s never successfully installed.
