Hi,
I see that your cart and checkout pages issues resolved.Please use custom css code to remove breadcrumb. .woocommerce-page div#breadcrumbs{display:none !important;}
Thanks
Mohammad
The shop / checkout / cart pages are all generated by WooCommerce. You need to set these pages in WooCommerce Settings (as detailed in the documentation). They don’t have any meta options, and any options they do have are in the Theme Options.
The admin link above doesn’t work, else I’d check the modal links.
