Howdy Marv,
I’m sorry to hear this is giving you troubles.
I’m not aware of any bugs that would cause overselling. There is however one feature that might be confusing things and causing this by accident. If you’re running WooCommerce orders do not get automatically approved. When a customer places an order for tickets it is pending until you go in and approve it. Keeping that in mind consider how it impacts the plugin: Say you have a stock count of 100, and 100 orders pending. Our plugin does not say “sold out” until everyone of those 100 pending orders are approved. Thus a few more people might come along and purchase tickets and thus further increase your pending orders. This is to prevent fraud. Otherwise a malicious person could purchase all 100 tickets with fradulent billing info, and cause your site to be sold out until you discover the error. To prevent this you need to watch when approving order, and make sure not to approve more orders than you have stock, just like you do with any other sales in Woo. Or if you don’t wish to approve orders you should setup Woo to auto approve and bill people when they checkout.
Does that sound like it might be the issue?
Cheers!
