Questions and answers
Before you buy
Klass: Which payment providers does Klass support for selling courses?
Paystack, Flutterwave, Stripe and PayPal, plus invoice and manual payment.
Licensing
Can I install Teragen extensions on client sites?
Yes. Every Teragen extension is licensed under the GNU General Public License, version 2 or later, so there is no limit on the number of sites.
Does an extension need a licence key to run?
No. The download key in your Teragen account is only used by Joomla to fetch updates. The extensions work fully without it.
Billing
What does the support renewal cover?
After the first year, $50 every six months renews support and access to updates. If you stop renewing, the version you have installed keeps working.
How do I pay?
Payment is taken through Flutterwave's hosted checkout. Prices are in US dollars.
Updates
How do updates reach my site?
Copy the download key from your Teragen account, then in your Joomla administrator open System, then Update Sites, choose the extension and paste the key. New releases then appear with your other updates while your support and updates are active.
