All websites powered by your Webasyst account are set up in the Site app.
In order to delete an unnecessary site; e.g., the one located on your account's service domain like ***.webasyst.cloud, proceed as follows:
- Click on that domain in the sidebar of your Site app.
- Open "Settings" section.
- Click "Delete entire website" link. All settings you have saved for this site (domain) will be lost with an option to restore them: pages, site structure, personal account settings. All saved data and settings of all your other sites (domains) will not be affected in any way.
If all you need is to replace the service domain ***.webasyst.cloud with your registered domain name, then follow the instructions from the article about linking a domain name to a Webasyst Cloud account.
