Strange cookie/session expiration
-
From WooCommerce 6.5.1 and 6.6.0, I think something has happened to the session handler. When I’m rolling back to 6.5.0, it works better but something still is weird; it takes a little bit longer before the problem occur. It is described like this:
* Put a product in the cart.
* Go to the cart review page. For 6.5.1 and 6.6.0, the session seem to expire instantly and the cart goes empty. Going directly to the checkout page has the same result but depending in the gateway I get noted about the expired session too.For 6.5.0, this is slightly better and it takes up to a minute before the session gets invalidated. I’ve tracked the issue down to class-wc-session-handler.php at this control where the session/cookie goes invalid (so for this case I’m trying to shop as a guest):
// If user has logged out, session cookie is invalid. if ( ! is_user_logged_in() && ! $this->is_customer_guest( $this->_customer_id ) ) { return false; }I however currently don’t know why this happens, except for if I roll back the woocommerce furthermore, the problem vanishes entirely. I run a test platform with WP 6.0, and when I disable all the plugins except WooCommerce, it also seem to work better. But with no plugins enable, the purpose with WooCommerece also slightly changing 🙂
Do you have any advice of how I can test for more errors and eventually make the user session not go invalid?

Yes, during tests woocommerce has been the only enabled plugin, without any caching, together with one other plugin that I’ve been working with for a long time (without changing any part that handles session related code).
Currently I’m trying to figure out what makes the session invalid, together with the plugin we’re developing. We usually don’t handle sessions at all from the gateway plugin we’re testing (mostly since it tend to break others), and instead we let woocommerce handle those parts. The problems also seem to escalate in the most recent versions of woocommerce, but I can’t find out why. I tried some theories yesterday, but that did just slightly help to keep the session alive a bit longer. I’m not sure what can possible invalidate a session, when it’s only handled from woocommerce.
Also, there’s no indication from error logs that code are breaking either.
Hi @tornevall
… if I roll back the woocommerce furthermore, the problem vanishes entirely. I run a test platform with WP 6.0, and when I disable all the plugins except WooCommerce, it also seem to work better.
This seems to be happening due to partial/improper compatibility with one or more of the plugins present on your site. It could be the theme too.
As Roxanne suggested above, we recommend performing a full conflict test to try and narrow down to the potential culprit, which is causing this to happen. This will involve deactivating all plugins apart from WooCommerce and switching to a default WP theme like Twenty Twenty-One or Storefront. Once done, reactivate the theme and other plugins, one by one, all along checking if the issue returns, to find the plugin (or the theme) that’s causing it.
Here’s the conflict test guide for reference: https://docs.woocommerce.com/document/how-to-test-for-conflicts/Do let us know how it goes.
