We’ve been getting reports of a really weird problem from some people. The problem is:
When you click “add to cart”, the cart widget is updated but as soon as you move to another page (or refresh the page) the items in the cart disappear.
Weird, eh? Also very painful because it is an isolated issue that affects on a few people.
How to fix this
This issue affects only some people on some webhosts. We do not have a full list of affected webhosts but here are two:
Please note that this is not to say that these webhosts are bad in any way.
The problem occurs because the session is not stored and therefore the data in the cart is lost upon refreshing or moving to a new page.
To fix this issue, you need to contact your webhost and ask them to enable session.save_path by editing the php.ini file.
