Thanks for your answer. Fair enough only / is checked.
I don't know all my custumizations by heart and should have known before upgrading to v5.0.
After upgrade Pihole isn't upgraded.
I will open a new topic.
Update:
After reading Installation beta - #5 by Bat I understand the version number is not 5 but 4.3.2
Is my pihole installation up to date now?
