I have a domain www.tahirakram.com. I have configured blog.tahirakram.com with my posterous blog. For that I just added A record with the IP address provided by posterous. And it was working fine.
I want to make a site on www. Means www.tahirakram.com or tahirakram.com will point to my own hosting. For this I registered a hosting account on 000webhost. I added their nameservers.
But now my subdomain is not working. Only www.tahirakram.com points to 000webhost. Rest nothing. Even without www its not working. And subdomain too.
