I'm not sure why but this error just started up today. No matter which category of product I try to add to the cart, it just says the category isn't valid. I went to the admin and updated the categories and it still won't recognize them consistently. I might try adding a dozen products and 10 of them will say the associated category wasn't valid. If I go back and try it again, it might work, it might not. Is this some sort of glitch?
is the URL of the store. Thanks
