This forum is only for reproducible bugs with csf and lfd (i.e. not iptables problems, lack of understanding how to use a feature, etc). Posts must be accompanied with full technical details of the problem and how it can be recreated. Any posts not adhering to this, or not considered bugs, will be moved to the General Discussion (csf) forum.
We've added two new settings in csf.conf to make the group ownership and chmod value configurable for the next csf release. In the meantime, if you pre-create the MESSENGER_USER public_html directory as desired, csf won't overwrite existing group ownership/permissions.
