Permission Problem, Error: internal server error, cannot start gmsrvs

[scriptbee]

HI Guys!

I've used the php7.0 version from will2therich and have only 1 problem remaining.
The Site/Script always tries to use www:data as user and group, instead of web1:client1 , which
ispconfig is using. I know this, because after i've created a new gameserver, it has it done with www:data .

If i try starting the gameserver, it gives a permission error.
but where to hell is www:data defined ? All permissions are web1:client1 and i cant find the string www:data in a File of the Gamepanel neither in the database ??

Is it somewhere hardcoded or where it is the user/group defined?

Would be very glad if somebody could help me,
thanks ricardo
