How to SYNC An Expired License That Shows Active
Posted by Jeff B on 18 February 2010 04:37 AM
After verifying your license is paid up to date and ACTIVE within our cPanel licensing servers (http://verify.buycpanel.com), please try running the following command to re-SYNC your cPanel license to the BuyCPanel licensing servers.

The following script should be run inside your server’s SSH, while logged in as ROOT: /usr/local/cpanel/cpkeyclt

Please remember, cPanel requires the use of a full-qualified hostname (server.domain.com) to identify your server. If this has not been set on your server you may also see a ‘license expired message’ within your cPanel or WHM. To check if you have a fully qualified hostname, run the ‘hostname’ command within SSH to check your server’s hostname. To set a hostname type ‘hostname yourserver.yourdomain.com’. Your hostname should also be registered in local DNS at your datacenter provider.
