Update the code below:

$('form').on('submit', function(e) {
e.preventDefault();     
if(!validateForm(this)){
return true;
}
var formdata = $(this).serialize();

$.ajax({
        type: "post",
        url: "http://www.example.com/client_config_send2.php",
        data: formdata,
        success:  function(data){
            alert("Thank you, we will get back to you shortly");
}
        });

})
