Yes, this was the only problem
Uhm, is this also normal? I means the double / between froxlor and install ?
php /var/www/froxlor//install/scripts/config-services.php --froxlor-dir=/var/www/froxlor/ --create
Looking at all the settings to check all new ones out and if I find smth. wired, I'll post it here ok?
