title: woocommerce add-to-cart empty
body: <p>I got the problem that when I click add-to-cart as guest customer, the cart always says empty</p>
  
  <p>but it's all fine with when I'm login as admin</p>
  
  <p>My server using varnish , nginx, php-fpm
  and I add varnish conf and nginx conf for woocommerce to not cache</p>
  
  <p>and I also has change the session.save_path to /tmp and set the permission to 777</p>
  
  <p>but all of this doesn't work</p>
  
  <p>my boss told me to get shop on-line in two weeks, I've been working with this issue for total 1 week,</p>
  
  <p>what should I do, or something I need to check???</p>
  
  <p>I think the problem will be the cache or the session</p>
