Magento Upgrade 1.7 > 1.9 DB Issue
问题 I upgraded Magento 1.7 to 1.9 and after upgrade the add-to-cart doesn't work anymore. It is not connected to the form_key! Why i think it is a database issue: I used clean magento 1.9 with clean database and created one product, add-to-cart works fine. I connected this magento with the database i upgraded and add-to-cart didn't work. So clean Magento with "old" database doesn't work on add-to-cart. Has anyone an idea how to solve this? I don't really want to use a clean database and move data
