Kentico CMS requires an appropriate license key for every domain you use. The licenses can be managed in Site Manager -> Licenses:

 

 

The list displays the information about licensed domain, expiration and edition. When you get full or trial key for a particular domain, you need to click New license and enter the full text of the key into the field.

 

How licensing works

 

If you're running web site on domain mydomain.com, you need a single license key that will also work for:

 

If you use a domain alias (domain name that points to the same web site), such as mydomainX.com or mydomain.net, you also need license keys for these domain aliases. You need to ask Kentico support for generating the additional keys (they are free of charge if you already own a license for the main domain).
