If you need support from Yola please contact us via firstname.lastname@example.org or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
A custom domain name has a yearly fee. If you cancel your domain, you can still build websites (up to 5 on a Yola Free account) and publish to a .yolasite.com domain, or purchase another custom domain name.
To answer your question, once you purchase a domain name, unfortunately, there is no way to change it.
Are you wanting to publish your site to a domain name, or do you already have it published?
