for example, I have changed domain but I cannot access the editor to add the new domain to the website
Hi, if you log into your account at Moonfruit.com and click 'Domains' you can choose which site to connect your domain to using the drop-down menu (if the domain was purchased with us). If the domain is with another provider and you are having trouble accessing the editor, it might be because of the preferred site address you have set. In this case, please contact our support team who can help.
