Hi, how are you?
After updating to 7.4, product variations are no longer selected, preventing you from adding the product to the cart. Only the first variation selects and the following ones do not. They deselect after being clicked.
Another problem is that the first selected variation is locked, we are unable to change the variation.
I have already deactivated all plugins, leaving only woocommerce and Woodmart Core and the problem continues.
I activated Storefront and the problem was resolved, that is, it is a problem with woodmart 7.4
Any solution?
