How to change the domain name after wrongly entered

Hi i just entered a domain name without reading to much about what to do, yeah shame one me…
But how to change it into for example just to test thing out.

thanks !

To “book” a domain name ended by, you have to indicate it at the postinstallation step.

Please reinstall to try it out :wink:

Ok i reinstalled it but… you can’t choose it gives errors
you can only choose and nothing in fornt of it.

so that’s strange because here it is stated otherwise
