Not sure what’s happening here and can’t seem to find much online about it.
I have a client site where random items are being added to carts, including my own. It seems as though the cart is “global” and any items added to the cart by anybody are being added to everybody’s cart including my own account. Random items keep popping in to my cart.
It’s not ideal as they have just dropped a large amount of new stock and have had a decent spike in traffic.
I doubt it’s an issue related to a Roots product. Nobody else has ever described this issue as far as I know, and quite a few Roots users pair our products with WooCommerce.
Try disabling all of your plugins and then re-enabling them one at a time until the problem is reintroduced.
