Have you set up your DNS? Bravo ! All that's left to do is to check that everything is good before taking Plezi in hand :) 

A sub-domain is an extension of your domain name. For example, content.plezi.co is a sub-domain of plezi.co.
You, or your webmaster, have created your DNS by following the implementation guide that was given to you, as well as this article.
By following the Implementation Guide, you have set up 7 DNS at your domain name manager (Gandhi, OVH, etc.). 

Are you sure that ALL your subdomains have been created?
