If you activated the automated invoice cancellation you may want to check first which invoices would get cancelled.
The module does have a test mode integrated. To run a test, please process as follows:
- Open an invoice at the WHMCS Admin
- Click on "View as Client"
- Add the parameter
&testAutocancellations=1
at the end of the URL.
The result should be: whmcs.yourdomain.com/viewinvoice.php?id=12&view_as_client=1&testAutocancellations=1
After calling the URL, the cancelled invoices are logged to your WHMCS Activity Log Utilities → Logs → Activity Log.
You need to be logged in as admin, otherwise, the test mode does not execute.
