I'm new to Magento and am taking over the work of another developer.
Previously I was creating simple, grouped, and configurable products with a manufacturer attribute. My goal was to use it as a filter option on the front end, which was working properly until recently.
The problem is in the Admin view the 'manufacturer' attribute is no longer showing as an option for ALL simple products, existing and new. It is only available for configurable products. Also the attribute has disappeared from simple/bundled products that had the attribute working properly.
How do I make the 'manufacturer' attribute available for all product types again?
Note: I've already gone to category_eav_attribute, and made sure it was apply_to=simple,virtual,bundle,downloadable,configurable
Thankyou for helping filme fast team to solve this..!
