It is not just a matter of creating a "cgi-bin" directory — for example, some hosts configure the server so that it will run scripts only from a particular directory outside the web directory structure (for security reasons). Your web page will still call the script "/cgi-bin/script.pl" but the server maps it to the actual directory.

Any syntax errors will cause a 500 Internal https://mediatemple.net/community/products/dv/204644990/why-am-i-getting-a-500-internal-server-error-message Server Error message to be displayed instead of your website.
