I’m getting an error ‘Parameter Missing or Invalid: Required parameter missing or invalid: items’ when adding any product to the cart.

Does anyone have any help for this? It’s a brand new website with no sales so far.

This is the error message:

When trying with the following the cart and checkout works:

custom-bat-builder?variant=42145414185201

£230.00
Grade Willow: Grade 1
Weight: Medium 2lb 9oz - 2lb 10oz
Bat Size: Standard Short Handle
Toe Shape: Round
Middle Position: Mid
Face Profile: Round
Anti Scuff Sheet: None

With products/low-density-cricket-bats the error happens
This is happening due to the id input being disabled so no “items” are being passed as parameter of the form:

In the main-product template this needs to be corrected.
Often this is due to adding some sort of stock logic, or app that handles products needing to make sure invalid items are trying to be added to the cart.

If the app is the issue source it can help to make an alternative template either for those products the app manages, or for the standard products.

If you need a quick assist to look through the code for that “disabled” source contact me.
