You can easily remove a website by removing an addon domain for it. In order to do so, open Hosting → Manage:
Scroll down and you will see Add Website section:
Once there, select the domain you wish to remove and click on Delete:
After clicking on Delete you will be presented with a warning, make sure to read it carefully to understand all the consequences of removing the domain from a hosting plan. Keep in mind that this action is not reversible and all files, databases, emails, and any configuration will be lost. In case you need backups before removing an add-on - be sure to download them beforehand. Once that’s done, click on Delete add-on:
That’s it! Now you know how to remove add-on domains (websites) from your hosting plan 😊
If you are removing the main domain of your hosting account, a new main domain will be set (the next one from add-on list). If there is no addon, the whole hosting account will be canceled.
