Please, try to format your post better. It seems you know how HTML works so it shouldn't be a problem. Also, please remove links to your provider's support channels.

What webserver do you use?

Where does your Perl look for modules? Is CGI installed there? It's not a core module any longer.

What bug in 5.26.3 are you talking about?

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

    A missing CGI.pm could indeed be a pitfall when upgrading from Perl 5.10 to Perl 5.26 - but the code snippet doesn't even use it... So I rather guess it's something more fundamental: a bad web server configuration, or Perl installed in a non-standard location, or file permissions - hard to guess without seeing the config.
