We performed an upgrade form V6 to the latest version 7. All appeared to go well until the cron run.
We have many One Time Products and Addons. The system generated new invoices for all these products, every one, even some going back 6 years ago, with a due date of year 2000.
Does anyone know under what conditions WHMCS will send recurring invoices for Products that are set a "One Time"
I see a new product status called "Completed", but cant find any documentation about it.
