open_basedir restriction again with webmail after upgrade
Hi, We just did an upgrade from 2.x to 5.0.3. Everything seems working fine but the webmail. While trying to access http://webmail.domain.com it gives error:

Warning: open_basedir restriction in effect. File is in wrong directory in /home/psa_home/vhosts/webmail/horde/lib/Registry.php on line 4


I know how to fix with vhost.conf but in this case, i don't know where to put vhost.conf. Any help would be appreciated.
