cross-sub-domain include path

[janjoh]

Hello!

I am trying to migrate an old website to my Plesk instance

On the old system it was divided into two domains.

galleri.domain.net

and

gallerimaster.domain.net


galleri.domain.net used include_path to be able to read from gallerimaster.domain.net but this i cannot get working under plesk.

I have a website (domain.net)

under it i have created two subsites (galleri) and (gallerimaster)

In the config for galleri i have changed "include_path"

/var/www/vhosts/domain.net/gallerimaster.domain.net/web:.

and yet it flunks with

[Sat Jan 24 11:45:03.768865 2015] [:error] [pid 16581] [client 213.114.166.188:54442] PHP Fatal error: require(): Failed opening required '/var/www/vhosts/domain.net/gallerimaster.domain.net/web/main.php' (include_path='/var/www/vhosts/domain.net/gallerimaster.domain.net/web:.') in /var/www/vhosts/domain.net/galleri.domain.net/web/main.php on line 3, referer: http://galleri.domain.net/

I have various combinations of open_basedir and include_path, but i cannot seem to make plesk let me include files from another subdomain

I am the server admin for the Plesk instance.
