If your site is published to a subdomain and you would like to publish it to your custom domain, please follow these steps:
1. Go to My Yola and click Domain settings next to your site's URL.
2. In the Add an existing domain section, select the domain you would like to associate with your site.
3. Click Add and then click OK.
4. The Current domains associated with your site section will display the domains you have published your site to.
Your site will then be published to your domain and your subdomain.
If your site now redirects to your subdomain, take a look at this tutorial: My domain is redirecting to my Yolasite subdomain.
