Hello, @USSH,
The page cart and checkout are coming from the WooCommerce plugin and its default WooCommerce plugin functionality our theme does not have any influence on it. Please try to check it once by activating the default WordPress theme like “Twenty Twenty Two” just to make sure that the issue is with our theme or not. If the issue persists with the default WordPress theme as well then it makes clear that the issue is not because of our theme and you have to contact WooCommerce support for it. Otherwise please share the FTP and working WP Admin Credentials with us.
Regards 8Themes Team.
