Hello,

Have you tried restarting CSF and then LFD (I apologize if that is what you did already)? Restarting CSF may resolve the problem here.

Hello,

The error message suggests another application is modifying your iptables firewall rules. You can try restarting CSF to see if that addresses the issue. In addition, feel free to report this issue to the CSF support forums at:

General Discussion (csf) - ConfigServer Community Forum

Thank you.
