"A valid license is needed to add new trial terms"

Enter your key in the License box on Packages > Trial Products and click Save & Check. If it says Domain Invalid, reissue the license in your K & K client area first.

A trial didn't convert or cancel on time

Check that Blesta's cron is running. Trial changes and reminder emails run with the standard Blesta cron.

The service canceled when it should have converted

Check that "Do not renew, cancel at the end of the initial term" is unticked on the package. That setting overrides every term on the package.

A trial is flagged "adjust invoice by hand"

The renewal invoice was partly paid or includes other services, so the plugin left it alone. Edit or void the invoice in Blesta yourself.

A client got a second free trial

The one-trial limit is per client account. A client who signs up with a new account can get another trial.

The plugin won't install

Trial Products needs ionCube Loader v15 or newer and PHP 8.3. Ask your host to enable ionCube for your PHP version.
