I've installed the domain mapping plugin correctly, putting sunrise.php in wp-content, adding the line to wp-config and the files to the plugins folder.
When I access 18.104.22.168, it ges to my main site, so it's working fine.
I've created a new site, portugal.maxistore.com.br which works fine exept when I map it to maxistore.pt. Going to maxistore.pt redirects me to maxistore.com.br...
This is how my DNS zone looks like: http://cl.ly/283l193G1R242P0F2d2y
