While we have tested the checkout on our side with the theme. The functionality is found to be working fine.
The checkout page for the products is set by the Woocommerce Plugin itself and contains the “[woocommerce_checkout]” shortcode to correctly load the checkout. Please make sure that your Checkout page is created and has the necessary shortcode in it.
Also, please make sure that your correct cart and checkout pages are set in the Admin Dashboard > Woocommerce > Settings > Checkout > Checkout Pages.
Please provide us your website URL if the steps above does not resolve your issues so that we could inspect the issues further and provide a fix.
