CPanel Trial warning with valid key

Is Cpanel/WHM incorrectly displaying a trial warning on login? Here’s how to fix it.

First things first, make sure you have a valid CPanel/WHM license and it is registered to the correct IP.
If you have confirmed that your license is active, and registered to the correct IP address, run the following command from a console as root:
/usr/local/cpanel/cpkeyclt
This should update the license information, and removing the incorrect trial period warning.
That’s it!
