If you are referencing your cgi-bin script with this URL:

http://www.yourdomain.com/cgi-bin/script.cgi

you are not using the correct URL to access your personal cgi-bin.

You need to use:

http://www.yourdomain.com/cgi-yourdomain/script.cgi

For example, if your domain was abc.com, and your script was named formmail.cgi, you would use:

http://www.abc.com/cgi-abc/formmail.cgi

If your site/script requires cgi-bin in the URL instead of cgi-yourdomain, let us know and we can set that up.
