Plus and Minus on Checkout page

It seems like there’s no quantity box on your theme’s checkout page. If there was one, you’d see the plus and minus buttons next to it.

Hello, I have manually customized the review-order.php template. Can you tell me what I need to add to the template so that the quantity block will be displayed?

You should reach out to the support team for your theme. This is not related to our plugin.

I’ve added a quantity block, but it doesn’t work. In the console I get the error https://webproff.eu/luxador/wp-admin/admin-ajax.php 500 (Internal Server Error)

I can provide the necessary login details, code snippets if needed.
I’ve been racking my brains for 24 hours and can’t solve this problem ??
