Upgrading from 1.4 to 1.7 and currently stuck at 1.6 file
Error in file: "/home/*/public_html/test/app/code/core/Mage/Sales/sql/sales_setup/mysql4-upgrade-184.108.40.206-220.127.116.11.php" - Column "base_shipping_hidden_tax_amount" does not exists on table "sales_flat_creditmemo"
So I tried adding that column and now get
SQLSTATE[42S21]: Column already exists: 1060 Duplicate column name 'base_shipping_hidden_tax_amnt'
So my question is: What does it want and how do I fix that?
