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.
Just done some rebuilds and some csf security checklists show suPHP enabled and some don't, yet it was enabled on all and the builds were clean... confused! All are on PHP5
Are you using the deprecated Apache v2.0 or the support v2.2? If v2.0 then there are some issues with the detection in csf. IMO, wouldn't recommend using v2.0.
