it seems that some one has pointed the domain cagurt. com to your site and the domain is behind Cloudflare you will have to fill a complain with Cloudflare and ask them to remove this dns point
The host/your website should be set up to only respond to certain HOST header values to prevent someone from pointing DNS to your IP and being able to effectively copy your website.
This is possible even if the domain is not being Cloudflare - see https://_concept.ytadid.com/ (bypass security warning). It is a direct CNAME to your domain (no Cloudflare proxy) and your web server is responding to it.
You should talk to your host about fixing this HOST header issue.
