Duplicate Invoice Numbers

IT also happened on our website, for orders created exactly at the same time.
Not only the invoice number as the same, but the order description and client info as well, which is a major problem, sharing personal information from one client with another.
Any help with this would be much appreciated.

Same thing – donors via WooCommerce Subscriptions who are renewing a donation overnight are all getting the same PDF Invoice number, and all getting the same PDF that’s been created (presumably for whoever was first). This means a PDF Invoice containing name & address details is being sent to the wrong people. An urgent fix is required, it’s apparently been happening since December 2019. We have disabled this plugin as it is potentially a major privacy issue.

The issue happens when you have a lot of post data in your database and have relatively slow server. We are aware of this issue and it will be fixed in the next update which will be released as soon as possible.

In the meantime this issue could be resolved by allocating more memory or by cleaning up your database by removing old data.

Also make sure to remove the emails from the Attach to Emails setting. This way no pdf invoice will be generated. Next up just generate the pdf invoice manually within the Edit Order page.

Can you let me know your plugin configuration settings by going to WooCommerce > Invoices > Debug and copy/paste the settings? I will be able to reproduce the error based on your specific settings.
