well, it should not

so what is the point to enable Cgi for somebody.[/quote:fa1402b80d]
Check your httpd.conf and access.conf to see if you have CGI enabled server-wide:
Options ExecCGI Includes [...other options]
When you uncheck the cgi option for a new account, WHM disables the cgi by overriding the server-wide config with a single line in the virtualhost container:
Options -ExecCGI -Includes (No CGI and No SSI)
You can tailor it if you like:
Options -ExecCGI (No CGI but SSI is ok!)
Options -Includes (No SSI but CGI is ok!)
