Hi admin-9453,
Thanks for reaching to us.
1. You are using WooCommerce Blocks. You need to remove them completely – https://monosnap.com/file/DYynCYO5DELtMiDQW2E99Yhx3TFPCs. Then define the Shortcode element with [woocommerce_checkout]
, save the page and as a result, the default template for Checkout page will be shown. The same goes for the Cart page.
2. You should Purge cache from plugins / CDN or disable it and check again, deactivate all plugins (except Required Plugins) and then reactivate them one by one. This makes it very easy to isolate the plugin causing problems.
