To enable UpsellPlus Checkout Upsells for your Shopify Plus store, you must have the checkout.liquid template file available in your theme.

To enable the checkout.liquid file:

Online Store > Themes > Actions > Edit Code

On the left side, you can see a checkout.liquid file under 'layouts' . If you can see this layout, then move along to step 2.

If you don't see the checkout.liquid layout click 'Add a Layout'. In the dropdown there should be an option to add the checkout layout. You can call it 'checkout layout-upsellplus'.
