Hi @Artiststable,
Thanks for writing in to our seller community 👋 I'm sorry to hear that trouble has brought you here.
If you're using a free Square subdomain, e.g mybusinessname.square.site, you can edit your site name by signing in to your Square Online dashboard and selecting Website > Domains. Click Edit next to your domain name > use a Square subdomain and make the appropriate changes. If you have purchased a domain with us, or elsewhere, and made a typo, you would have to purchase the correct domain name instead. Learn more about connecting your domain to your website here.
I hope this helps, please let us know how you go!
