Are your users using OpenDNS as DNS resolver? It seems as if they flagged your domain and redirect it to their anti-phishing page at https://phish.opendns.com/main?url=studiobookingsonline.com

Server:  resolver3.opendns.com
Address:  208.67.222.220

Non-authoritative answer:
Name:    studiobookingsonline.com

You can only submit a fix on their site. On the side of Cloudflare you could only enable DNSSEC but that would not fix the issue either.
