not subdomain works

I have al configurated in cpanel with subdomain m.movilmaniaco.com and checked in mobile joomla setting the ticket in "Domain (multisite) support" with "YES"

I haved follow the video with instruction but not work...

what another configuration I must to have?

I cannot resolve and ping m.movilmaniaco.com (at the same time there is no problem with pinging movilmaniaco.com), so first of all check that you have corresponding record in DNS.

Hello,
I installed the MJ and works very well. I wanted to add a subdomain and got a problem: my provider (www.000webhost.com/ Free account) CPanel doesn't allow me to do "redirection" I MUST use the 'm' folder:
mysite.com -> /public_html/
m.mysite.com -> /public_html/m/
So... How can I get around this problem ?

Thanks in advance

Usually cPanel allow to modify DocumentRoot at creating of subdomain, so just click on this field (it will be autopopulated at this moment) and remove /m from DocumentRoot before push Create button.
