Custom base: /%product_cat% is not working for product permalink. It return 404 Not found for all pages!
This happened while moving from 2.1.1 to 2.1.2.
I have Yoast SEO installed with “Redirect ugly URLs to clean permalinks” turned off.
If /shop/%product_cat% or /anything/%product_cat% is used, all pages show up fine. It’s just /%product_cat% that would lead to all pages giving “Not Found”. I guess, something got messed up with permalinks in 2.1.2
