I made a change to the number of temporary IPs that can be blocked in my CSF firewall yesterday -- and everything was fine. Went in this mornign to check on it, and received a 500 error. I believe that WHM/CPanel was just updated. The log shows the following error: [Tue Oct 12 11:02:12 2021] csf.cgi: Can't locate Cpanel/cPanelFunctions.pm in @INC (@INC contains: /usr/local/cpanel /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/local/cpanel/whostmgr/docroot/cgi/configserver/csf.cgi line 17.

Advice? Thanks

  Hey there! I have a machine with CSF and I am not seeing any errors in the WHM interface with that tool. You may want to try running this command just to ensure there is nothing missing on the server-side: /scripts/check_cpanel_rpms
  If that doesn't resolve the issue, reaching out to CSF directly at ConfigServer Technical Support would be the best option as that isn't software we create or distribute on our end.

  After doing a reinstall / upgrade of CSF, the problem cleared up. I don't know if this is just my provider, but I had a script csupdate that was in my root directory. After reviewing the script it was set up to update the CSF software. I ran the code, CSF was updated and the CSF config page came back up.

  I'm glad that's working well now!
