I suddenly got a problem with variable product today. When I add a product (variable type) in shopping cart and view cart, there is no info in 'Cart Total' section. The problem does not happen with normal product and Cart Total info still visible at Checkout page.
I tried to deactivate all other plugins but the problem still retain.
I have 2 environments of Woocommerce. One is live and another is localhost for testing purpose. The problem also does not happen at my localhost environment.
