Cgi Script Error

of questions I get from my visitors at thesitewizard.com, I can see that one of the most dreaded errors that newcomers to CGI face is the "500 Internal Server Error". It is one of the most uninformative error messages that can mean anything from an

improper upload to a bug in the script. This article attempts to give you some concrete, internal server error cgi-bin apache practical steps that you can take to narrow down the problem and hopefully eliminate it. For the uninitiated, a "500 Internal Server Error" is cgi script internal server error a message much like the common "404 File Not Found" message. You get the latter message in your browser when you try to access a non-existent web page. You get the "500 Internal Server Error" message when you try to

run a script with problems. For the purposes of this article, I am assuming that your CGI script is a Perl script, by far the most commonly available on the Internet. We will try to eliminate the most common errors first (and the easiest-to-eliminate ones): Location Did you upload your scripts into the right place? This is not as obvious as it may seem. Some servers are configured to run your CGI scripts anywhere. Others will only run it when

it is installed in a particular directory. 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. You will have to upload it in the right directory, regardless of what your web page calls it. Find out such information from your web host's documentation. File Upload Mode Did you upload your Perl script in ASCII mode? Your FTP client may have uploaded the script in binary mode if you did not take any special action. Perl scripts are ASCII files, and since different operating systems have different ways of representing the end of line character (eg Unix uses a line-feed, Windows uses a carriage-return and line-feed pair), it is important that you set the uploading method to ASCII, so that line-end translation is performed. Re-upload the script, this time making sure that it was uploaded in Text or ASCII mode. Do not use any auto-detection options since the FTP program might assume the extensions you are using for your scripts are for binary files. File Permissions Did you change the permissions on your script so that it can be executed on your web server? In most cases, simply uploading the Perl scrip

server found a problem with the permissions on your script. For security reasons the cgi internal server error web server performs a couple of security checks on scripts before they are being executed. In most cases you want to check the http://www.thesitewizard.com/archive/servererror.shtml scripts permissions and see whether it is set executeable it is not writeable by anyone else than the owner (not even the group which is the default) In your log directory you will find the suexec.log which contains an explanation of the problem. Note that the suexec.log gets https://www.greennet.org.uk/support/my-cgi-script-does-not-work-and-displays-500-server-error-message updated every couple of minutes so you might have to wait before you can actually see the log line explaining the problem.
