Recently, it’s been reported to me that customers are unable to add certain products to their shopping cart. From my own testing, it appears that this mainly affects products of the type “Simple Product”.
The most recent updates were to WP 4.7.4, WooCommerce 3.0.4, and Royal Theme 3.0.1.
The store is currently losing money due to this. Can you please help me ASAP. I’ve tried it with plugins deactivated.
In the Woocommerce status page, there are several messages stating outdated Woocommerce pages. One is cart.php. Could this be the culprit?
