hmm, I commented out that line in cgitrc and looks like the filter is
indeed the issue.

I checked, and I do have highlight installed (textproc/highlight)

from httpd-error.log:

I gave apache the correct permissions for the script but it still
doesn't display the file contents.
I looked in the bash script, and it says:

# This script requires a shell supporting the ${var##pattern} syntax.

I do have zsh + bash installed on freebsd, but apache is nologin? I'm
not really sure what that means.
Could that be the issue? And if so, how would i correct it?
