Can't get plugin to function correctly

Do you have any other plugins installed? WooCommerce by itself should be keeping people from buying more than the quantity in stock. This plugin is just to keep people from adding more than the available number of items into carts.

I would go under WooCommerce->System Status->Tools Tab
and click the button to “Clear all sessions”. If there are any abandoned carts with those items in them it could potentially cause issues.

Thank you for your prompt reply! I do have other plugins installed. I have been using woocommerce for my shop for a little over a year now, and if there are multiple people that go in at the same time and try to buy the same item, sometimes it allows them to if their payment isn’t already processed. It takes some time to get to paypal and go through the process, and when I release a new product email I get a flood of people trying to buy at once. I was hoping this plugin would eliminate that issue. Since only one of each item is always in stock, they’d get a “out of stock” warning instead of being able to add the same item someone else is currently trying to purchase to their cart.

I just tried the clear all sessions suggestion, and tried it again – unfortunately same thing. It’s saying the item is added to the cart, but the cart is showing empty. As I was testing it, I actually just had a customer email me and say the same thing just happened to her. Any other suggestions? I am so hoping to get this up and running! Thank you!

Yes this plugin should help with that issue, can you share a screenshot of your settings page? If you are using expiration with it the added to cart message should include an expiration time, are you getting that?

If you share the URL to the site I would take a look at it. If you don’t want to share it publicly you can email it to me [email protected]

What version of PHP, WooCommerce, and WordPress are you using? What are the other plugins you have installed?

I just sent you an email with all of the information you requested. Thanks!

Issue resolved in private email. Problem was WooCommerce 2.1.12 was installed which did not have the wc_get_product function. Upgrading to latest WooCommerce resolved the issue.
