Expire Time not working

Can you supply some more information? If there were items in the cart before this plugin was activated then they will never expire. Only managed stock items added to the cart after this plugin is installed (and configured) will be expired.

Any items that are in carts/sessions before the plugin was activated will not be touched.

Sorry James but thanks for the answer. I tried with all the items in general and nothing was inside the cart before I activated it. I also try to use it an user and as guest but the result was the same. I insert a product in my cart, waiting for an hour, refreshing (or changing page), entering in the page and my article was there

Can you take a screenshot of the plugin settings and specific product settings?

That’s a screen of the plugin settings https://ibb.co/dV3OWn
What do you mean with specific product settings?

The way a specific product is configured showing its quantity and if stock management is enabled.

This is the screenshot of the product I put in my stock https://ibb.co/fHBkBn

The plugin removes the product from my inventory if it is in my cart, which is amazing and very useful but if someone wants to buy that product tomorrow, and I forget to pay the last one, it’s not available in my stock but no one buys it

Those settings look good. How about under the general WooCommerce settings. WooCommerce->Settings->Products->Inventory. There is an ‘Enable stock management’ checkbox

Yes. It’s there. I thing the part of inventory is right, otherwise I should not see the number that goes down if I put an item in my cart

Ok, I somehow missed that part that the inventory count was working. What version of WooCommerce and this plugin are you using? You can try out the latest development release which has numerous improvements in it (https://github.com/jamesgol/woocommerce-cart-stock-reducer/archive/master.zip)

Okay I will try to be sure about! Thanks for everything
