Reply To: I need to update my theme template files….?

Hello,

“Please select some product options before adding this product to your cart.”

This is Woocommerce functionality. It means, if you have created a variable product based on two attributes, for example, color and size, you need to select both attributes to add a variation to the cart.

If you switch to the Storefront, you will see the same: selecting one attribute would show this error, and selecting both attributes would add a variation to the cart.

Best Regards
