After the last update woodmart (7.4.1) we have an issue with adding products with multiple variations. After you choose the variables from the product, the same error message.
“Please select some product options before adding this product to your cart.”
Disable all plugins except for woocommerce and woodmart core, still not fix
With default theme wordpress it’s ok.
You can fix it by applying patch # 527979. To do this, go to Dashboard -> WoodMart -> Patcher, find the corresponding patch and click on the “Apply” button. Let us know if it works for you.
