Enabling litespeed with trial.key

Hi,
How do I enable litespeed with trial.key?
I enter Cyberpanel (:8090/serverstatus/litespeedStatus) Only the license key can be activated. But a file called trial.key was sent to me by mail. Could you help ?

Not possible, you can use Free Starter.

1- Can I activate it with the license I received from Litespeedtech.com? Or do I have to take it from you?

2- Can I return to openlitespeed if I’m not satisfied?

  1. The key is eventually bought from LiteSpeed store.
  2. You will have to reinstall CyberPanel with OpenLiteSpeed.
