How to remove Trial

For yourself and everyone else who has this same question ....

The "trial" logos will disappear automatically when your license changes over from a temporary trial license to a permanent one.

However, once you have purchased a proper Cpanel license either through Cpanel directly, a Cpanel distributor, or your hosting / server provider then you can speed up the process by logging into SSH as "root" and running "/usr/local/cpanel/cpkeyclt" and / or doing a Cpanel update.

(Cpanel updates can be done from WHM or from SSH "/scripts/upcp")

To check the status of your license, go visit License Verification - cPanel Inc.
and there you can find out if your license is still on Trial or to see if a newer permanent Cpanel license is now active.

One very common mistake I have seen working in this world is for people to get a "Trial" license under their server's main primary IP address (first external IP listed when running "ifconfig") and then turn around and purchase a license for one of their web site IP addresses.

Cpanel licenses only work with the server's primary IP address so make sure that you do in fact have the correct IP address when setting up or verifying Cpanel licenses --- your server's primary IP address and usually also the shared IP for your server though sometimes different.
