Prepare Your cPanel Server for the ConfigServer Shutdown

System administrators using the third-party CSF and LFD plugin may sometimes experience errors with the plugin's features or functionality. Such errors may include--but are not limited to--these:

• lfd will not run with TESTING enabled
• SYSLOG Check Failed
• lfd.service failed
• Excessive Resource usage
• Country Code Filters setting MM_LICENSE_KEY must be set in /etc/csf/csf.conf to continue using the MaxMind databases

ConfigServer, the vendor for CSF/LFD, is responsible for errors and user-experience issues with their software. You can contact them for assistance here:

If they are unable to help due to incompatibilities with your server environment, or if your request is urgent and you need an immediate solution, you can consider cPanel-supported security extensions such as Imunify360 and ImunifyAV+, which you can read about here:
