If your invoices are still generated on your old template, it's probably because you are not a Nutcache PRO or Enterprise subscriber.

It may be that you created your invoice template during your PRO or Enterprise trial and once the trial ended you fall back to the default template, since Nutcache’s free version does not provide access to custom templates.

To take advantage of the custom template feature, you must subscribe to the Nutcache PRO or Enterprise version.
