Resolution
Reviewing the error log for CSF will tell you why it cannot start:
- Access your server via SSH as the 'root' user
- Review the contents of the csf log file for errors:
/etc/csf/csf.error
- The csf service may be prevented from restarting by several issues. You will need to address the issue individually to allow the service to restart.
- Once the issue has been addressed, restart csf and lfd with the following command:
csf -r
