I am using new version 1.4.0.1, recently i upgrade from previous version, the problem also in previous version
my problem is when i add custom option in new product its not appear in front end
for the previously added product custom option showing ok in front end
if i create duplicate product from previous product (with custom option) its working ok, there are only problem if i create new product and than add custom option its not showing up
there are also add to cart button not showing up if i add custom option in new product
i follow instruction in http://www.magentocommerce.com/bug-tracking/issue?issue=5120 but no luck because my catalog_product_entity already set has_options = 1
