Your website runs on a domain and hosting in your name. Vaultmastr doesn't sell or manage either.
- Pick a host that allows adult content and offers one-click WordPress. Website setup suggests one, with a Get hosting at ... button.
- Register your domain in your own or your business's name, on a registrar account that's yours.
- Install WordPress on the domain from your host's control panel.
- Check you can log in at https://yoursite.com/wp-admin.
Then install the theme and plugin: see Install the Vaultmastr theme and plugin.
Watch out: Check your host's terms allow adult content before you upload anything. Many mainstream hosts don't.
Some links on the Website setup page are referral links. Vaultmastr may earn a commission if you sign up through them. It costs you nothing extra.
