Fortunately, it’s very easy to avoid! By default, CloudFlare enables a subdomain for direct access to the shared hosting server – if your domain is example.com, then the direct access subdomain will be direct.example.com. So, for example, webmail will be accessible at http://direct.example.com/webmail. Alternatively, if you wish to use SSL to connect to services (recommended), you can use the primary hostname for your server, which can be found in Backstage (and was what you specified when you signed up) – as the primary hostname will be on a different domain, it won’t be affected by CloudFlare.
The direct access method can also be used during period of active development as it’s common to need to check the latest versions of scripts or graphics that are undergoing regular updates. In order to do this, the site can be accessed with the root domain, rather than with the www. prefix .
For example : http://yourdomain.com rather than http://www.yourdomain.com.
