How to I change subdomain folder root to another subdomain ?

[mickaelc]

Hello,

I would like to change the root folder of my subdomain
/var/www/vhosts/$domain/subdomains/$subdomains1/httpdocs

to

/var/www/vhosts/$domain/subdomains/$subdomains2/httpdocs

I created vhost.conf file on the conf folder of my subdomain:
/var/www/vhosts/$domain/subdomains/$subdomains1/conf/vhost.conf

I Added that line:
DocumentRoot /var/www/vhosts/$domain/subdomains/$subdomains2/httpdocs

Last step is to reconfigure sites:
/usr/local/psa/admin/bin/websrvmng -a

When I enter the subdomains1 url, the browser just download a file.
I think Php is not working...

Any ideas ?

THanks
