your scripts have this error on my server:
/scripts/makecpphp and /script/upcp --force did not solve the problem.Undefined subroutine &main::pwcheckos called at /usr/local/cpanel/whostmgr/docroot/cgi/addon_mailscanner.cgi line 22.
Internal Error: "GET /cgi/addon_mailscanner.cgi HTTP/1.1" Premature end of script headers: /usr/local/cpanel/whostmgr/docroot/cgi/a$
A manual reinstallation of cmm and cmq and an update of csf resolved the problem.
But... ConfigServer MailScanner FE still have the problem.
Because you installed it, I don't know how to solve this voor MailScanner FrontEnd.
May be you have hint.
Thanks.
