Hello @Ralphmyes,
Thank you for the inquiry.
Did you recently migrate the site to HTML storage? Try adding this hook in the functions.php file to manually set the page as checkout page.
function x_custom_checkout_page_check() {
$checkout_pages = array(
'checkout',
);
if (is_page($checkout_pages)) {
add_filter('woocommerce_is_checkout', '__return_true');
}
}
add_action('template_redirect', 'x_custom_checkout_page_check');
If there are other checkout or payment pages in the page, you can add them in the $checkout_pages array. Let us know the result.
Let us know the result.
