Changing domain name

Hi, I built this new site on another domain name. millenium-residence-bangkok.com and it’s nearly finished. I did a test copy to another domain, webgonzalez.me to see if there’d be any issues before I finally move it to samuielephanthaven.org. But I saw this error message on the copy to webgonzalez.me
Is that because of the licence key?

Thanks

Paul
