Hi!
We have a shopping cart that the “My Cart” button has a dropdown that shows what’s in the cart. We cannot seem to find where this Cart Dropdown is setup in our theme or apps.
The “Remove” link in the My Cart dropdown is not working and giving an error:
“Parameter Missing or Invalid(bad_request): Required parameter missing or invalid: ‘line’ or ‘id’ param is required”
Where do we find this code to fix? And, any suggestions on how to fix? We are using an old Testament Theme with a lot of customization, so we prefer not to change themes, but rather, to fix this issue. It is fine if we can simply remove the “Remove” links from the dropdown, but not sure where to find it.
Thanks for any help!
