[Solved] [plesk -> ispcp] Error: PRODUCT_ROOT_D

[vurte]

I installed ispCP Omega (nightly buil 2009-01-21) on 64bit ubuntu 8.04 (befor there was a preinstalled plesk on my root server, which I wanted to get rid of .....)

when I wanted to open the admin login page,
I got the Error 500!

and suexec: Error: PRODUCT_ROOT_D not defined
in default-error.log.

tail -f /var/log/apache2/users/default-error.log:

I googled and saw that plesk is using this environment value,
but don't know where suexe is requesting it and how to avoid this error.
