I’m sorry to hear you’re having trouble with WooCommerce tickets. Let me help you with this topic.
First, let me note that by default, cancelled orders will not automatically re-stock the tickets.
Depending on your WooCommerce specific settings, after you cancel an order, you may have attendee records generated for that order, in which case you’ll want to delete the those records. Once you delete an attendee record, the ticket stock will increase.
Doing some tests on my end I could spot an issue with tickets that have a shared capacity like yours, where deleting an attendee will not re-stock the ticket capacity.
I will set this thread’s status to “Pending fix” and link it to the report. We will notify you once a fix is released.
However, I’m not able reproduce the “Tickets sold” figure being zero. I’m not able to see your complete system information. Could you please share with us your complete system information by pasting it into a private reply?
Thanks for hanging with us on this issue. We’ve just released an update to correct the shared capacity calculations. As always, we recommend that you back your website up, test on a staging site, and then take it live on your own website. Let us know how it goes!
