www.Subdomain.Domain.com not working ?

You just need to understand that the 2 URIs are not the same:
www is a subdomain of news which is a subdomain of mbanetwork, so basically, you are trying to make a subdomain equal with a sub-subdomain.

You can educate your non-techie users… or you can try this:

thnks for ur reply

well u cant educate users can u , u can only adjust urself accordingly.

i asked this coz my friends blog hosted on another host re-directs automatically.

anyways how do i re-direct requests to https://www.subdomain.domain.com to subdomain.domain.com so tht users dont face issues ? pple have a tendency to type www and its not thier fault is it

You have to redirect https://www.subdomain.domain.xxx to subdomain.domain.xxx from you admin panel.
Add the https://www.subdomain subdomain (yes it is a a subdomain as a whole).

And go to daddy forum next time ??
