plugin[muli-Domains] issue in my new site

Hi support,

I installed 'multi-domains' in my new wordpress with mu, case below:

I create 2 sites with domain http://staging.she.com/clients/she.com/revamp/wpmu/v1(Default) and http://shemom.com/clients/she.com/revamp/wpmu/v1/shemom(new site), then I pointed domain 'shemom.com' to my server in local host table.
It redirect to default site when I paste the new site url on browser.

I already added record to default site domain's virtual host , something I missed?

Thanks
