Hi Alice-
Thanks for reaching out, and I’m sorry about the long wait to launch your website.
I checked out the domain name you sent over, and it doesn’t show up in WHOIS lookups, so I suspect that your domain registration has an issue. If you registered your domain via your WordPress Hosting provider, I would double-check with their support team.
Once your domain registration has gone through and your DNS (and redirects) have been set up, it can still take up to 24 hours for the DNS to “propagate” across the internet, but it’s generally much faster.
