Hey there! New to the family! :)
I set up my store 3 weeks ago! So you can imagine how I am feeling!
I checked my store to see how everything is running today! I noticed when I went to test add to cart from ios, the home page and product page it displays "Required parameter missing or invalid items" . I then checked on my laptop on windows/google chrome and the same error message came up on the homepage but not the product page! I was told it would take 1-3 business days for a reply! I really can't afford to wait this long! I am in a state of panic as I have expensive ads running and this is the last thing I need to be dealing with. Please Help! Cheers!
