Step 1: Update the License on Your Server
Once renewed, update your cPanel license by running:
/usr/local/cpanel/cpkeyclt
This will force cPanel to fetch the latest license data.
Step 2: Restart cPanel & WHM Services (if needed)
If cPanel still shows license errors, restart the services:
service cpanel restart
or
systemctl restart cpanel
Step 3: Verify the Update
Log into WHM and check for any errors. You can also verify your license via cPanel's License Verification.
