Please note that CNAMEs are settings that you configure for your domain (DNS stuff), it has nothing to do with the script itself or even your server settings.
That maps translate.chevereto.com to that onesky subdomain. CNAMEs are just any other DNS setting so it needs time to propagate. My recommendation is that you should use CloudFlare for DNS settings, is fast, easy and free. I have CloudFlare on Chevereto.com just for the easiness and fast propagation of the DNS settings, I'm not using their cache or CDN at all.
