Hello @rhhridoy ,
I hope you are well.
If your site was created in November 2023 or later, your site may be using WooCommerce Blocks by default for Cart and Checkout pages, currently, we don’t have compatibility for WooCommerce Blocks, but we will be integrating this very soon.
However, we have a solution for you and you can implement it in less than 5 minutes, it would be simply to use the WooCommerce shortcodes instead of WooCommerce blocks:?https://docs.athemes.com/article/how-to-switch-cart-checkout-blocks-to-the-classic-shortcodes/
Please let us know how it goes, and if you need further assistance, don’t hesitate to reach out.
