I’m redesigning this existing website. There are already variable products set up and some are using the Woocommerce product add ons function. All has been fine, until I installed Pro and now the variable options AND the adding are not working.
This is an example
https://iztechkartseats.com/product/iz1-kart-seat-t8-equivalent/
I’ve switched to a basic theme (twenty twenty one) and the products are fine.
Can you help please?
