I added some custom options to the product:
But the options are not visible in product page. Only description and regular fields are visible:
please check catalog_product_entity table and check has_options column for that sku
If it is zero then try to change 1 and check it
Hope it will help you
please check with default magento theme like rwd
if it is work with RWD then it is your theme issue
Hope it will help you.
