I will solve this not long ago :-)
I'm not sure if this is not a security hole but this work for me.
/var/ must have provileges 77x
/var/www/ 77x
/var/www/web4/ 77x
/var/www/web4/html/ 77x
and for all directories the group must be some group where "apache" is a
member of this group.
And at the end you MUST RESTART Apache ;-) because Apache is running using
privileges readed at start time.
