I'm using Magento CE 1.9 and my cart keeps emptying when I click on the cart page. This only happens on localhost and is not a problem in production (which uses SSL). Here's what happens:
- Add a product to the shopping cart
- Click continue shopping
- Product is in the mini-cart
- Navigate to the cart page
- Application immediately render the empty cart page (and mini-cart is empty as well)
I've tried changing the increasing the cookie lifetime to 1 day and setting Validate HTTP_USER_AGENT to yes. What else can I do?
