Magento 1.5 Shopping Cart Is Not Persisting Items

We are working on a Magento-based website that sells outdoor gear. We have discovered an issue in which the shopping cart is expiring in 30 minutes to 2 hours when it should be persistent for 30 days or until the customer places their order.

See http://www.usadventurer.com/

To reproduce the issue, simply try the following:

1. Add any item to your cart

2. Refresh the cart or visit any other page and verify that the shopping cart s开发者_C百科till has your item

3. Wait 30 minutes to 2 hours, refresh and your shopping cart will be empty.

The site configuration is as follows:

Magento 1.5.0.1

In .htaccess:

php_value session.cookie_lifetime 2592000

In Magento Admin Panel

System > Configuration > General > General - Locale Options:

Timezone is set to same as server (US Eastern Standard Time)

System > Configuration > General > Web - Session Cookie Management:

Cookie Lifetime is set to 2592000

System > Configuration > Sales > Checkout - Shoping Cart:

Quote Lifetime (days) is set to 30

We aren't sure what is causing this problem as the settings look good (though I think we shouldn't have to increase the session lifetime.)

Thanks in advance!

The solution was to increase the session timeout to 30 days.

That can't be the right answer you already said you did that in both Web - Session Cookie and Checkout - Shopping Cart.

Was flushing cache the trick?
