with more than 230 countries and for my part 10 different Shipping Method it's easy to forgot some configuration.


edit your ~/Views/Shipping/Restrictions.cshtml in project Nop.Admin with few jquery will prevent to loose business.



<script type="text/javascript">
        $(document).ready(function () {  
$("tr:not(.headerstyle)").each(function (e) {
                var t = $(this).find("input:not(:checked)");
                if(t.length==0)$(this).css("background-color","red");
              
            });
});
                    </script>

let's change CSS style and behavior with a .click on UI


hope this helps.
