undesired redirect

[DNK.it]

Hello,

today I've add domain name with ispmanager. If I digit www.domain.com in the browser bar I can see the domain directory content, but if I digit domain.com the server redirect me to domain.com/www.MAINdomain.com

and I get a 404 error

I've deleted and re-add the domain without success, checked the apache2.conf file and ispmanager.conf... all seems fine

Hello,
you need check WWW domain configuration (properties) for auto subdomains and disable it if this enable
