Checkout error – No products validated by crawler!

Hi everyone,

I’ve just noticed that it is impossible to complete purchases on my client’s e-commerce site: wetlands - home

During checkout, this error appears:

The order cannot be fulfilled.
No charges have been made. Please contact the store owner for more information.

Checking the browser console, I see:

app.snipcart.com/api/cart/.../pay:1 Failed to load resource: the server responded with a status of 400 ()
snipcart.js:1 A 'cart-confirmation' error occurred in Snipcart.
Reason: 'domain-crawling-failed'

Screenshot 2025-10-06 alle 13.34.42

Currently, none of the products are being read by the Snipcart crawler, so no orders can be completed.

Developer logs show this (first appeared on 22/09/2025):

Impossible to validate items for order '...'. Please make sure the URL is valid, see Security documentation.
Validating item with id '...' located at '...' on domain 'wetlandsbooks.com'.

The store was working correctly until recently. First abandoned carts were recorded on 02/10/2025.

Has anyone seen this issue before? Any idea why the crawler can’t read any products and how to fix it?

Thanks in advance!
