When a visitor first adds a product to their cart a session is started that, by default, lasts for 48 hours. When it expires, the items added to the cart are forgotten, meaning the next time that visitor comes by, they’ll find their cart to be empty.
The cart session is not related to the Inventory’s Hold Stock setting. The Hold Stock setting applies to orders of the Pending Payment status where inventory is removed, but payment is not yet confirmed. This snippet does not impact that setting nor vice versa.
Only new visitors are instantly affected by this snippet, as recent visitors could still see the contents in their cart until their existing session expires.

The value for this setting needs to be returned in seconds, which is why 47 hours is expressed as
60 * 60 * 47 (seconds x minutes x hours). To test this, for example, you might want to temporarily set it to 5 minutes, in which case
60 * 5 can be used instead. It’s best to not use such a short window permanently though as it would hamper the shopping experience and performance of your site.
Caching ↑ Back to top
To make sure the setting behaves as intended, refer to our Configuring caching plugins guide. If you encounter issues with lingering cartms, clear plugin caches, and caching that might happen at the server level (you may need to reach out to your host for help with the latter).
