All your domain configurations can be managed on your “Domains” page in the settings of WebDirect. In case you need help logging into your WebDirect please refer to this article.
Once you are on the “Domains page” in WebDirect, you will see two sections: “Primary Domain” and “More Domains”. When you hover the domain a button called “Remove” will appear. Once you clicked on “remove”, make sure you save those changes by clicking on “save”. Your domain is now removed from your WebDirect site.
