Just put the wraps on a quick how-to video on reissuing your license from Go Higher. This video shows you how to resolve the most common cause of an invalid license for a Go Higher product: server changes.
Our licenses are bound to the installation path, the IP address and the domain name. Should any of these change over time, the license will report as being invalid and you will need to reissue your license. Most frequently, a server may have their IP addresses changed, but this can also happen if you purchase an SSL certificate or change the installation path of your WHMCS application.
