In the backend of our ecommerce software which is based on a heavily modified oscommerce core we have a error with the link product in the copy product page
passworded: [url removed, login to view];pID=1475&action=copy_to
when you go to copy and select link instead of duplicate you get this error:
1062 - Duplicate entry '0-0' for key 1
insert into products_groups (customers_group_id, customers_group_price, products_id) values ('', '', '0')
I need the above problem fixed so that linking is functioning correctly.
