Getting wired error. When insert product and enter data in extra field it does not insert in product extra field table therefore it does not show on product page. If I go back to edit product, edit product page shows all fields blank/empty in admin. For some reason it is not inserting product/content to extra field table. How to fix it? If I insert info/product id to extra field table via cpanel/sql then all fields appear in admin edit product page.
