Your license key is in your WPInterface account and in your purchase receipt email.
- Go to WooCommerce → Paddle.
- Paste the key into the License box and click Activate.
The box then shows Active and when updates and support run until (or Lifetime license.). Updates come from wpinterface.com and appear on the Plugins screen like any other plugin’s. The license is checked again about once a week.
Without an active license
Everything keeps working. Payments, subscriptions, renewals, refunds and invoices don’t depend on the license. You only stop receiving updates and support.
Moving to another site
Click Deactivate first; that frees the site for your key. You can also manage your sites from your WPInterface account.
If activation fails, the box explains why, for example that the key has expired or has reached its site limit.
