Thanks for your replay Klayvo
I find the solution and it’s working well now. Change the js function from the following path
klaviyo\includes\js\wck-started-checkout.js
function setKlaviyoCookie(cookie_data) {
//comment this line
// cvalue = btoa(JSON.stringify(cookie_data));
cvalue = btoa(unescape(encodeURIComponent(JSON.stringify(JSON.stringify(cookie_data)))));
var date = new Date();
date.setTime(date.getTime() + (63072e6)); // adding 2 years in milliseconds to current time
var expires = “expires=” + date.toUTCString();
document.cookie = klaviyo_cookie_id + “=” + cvalue + “;” + expires + “; path=/”;
}
