I encountered a 500 error with the error message of ;

Internal Server Error

500

No response from subprocess (/usr/local/cpanel/whostmgr/docroot/cgi/addon_csf.cgi): subprocess exited with status 2

when trying to use csf (configserver & firewall) on a cpanel server via whm. I also got the following when trying to use it on the command line;

It turns out the fix is super easy and just requires an update. Run;

curl -s download.configserver.com/csupdate | perl

Then restart csf;

csf -r
