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 cgi internal server error 500 you some concrete, practical steps that you can take to narrow down the problem and hopefully eliminate it. For the uninitiated, a "500 python cgi internal server error Internal Server Error" is 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.

Learn More My CGI Script Generates An “Internal Server Error” Rate this Article Article Rating: 1 / 5 Votes: 21 An “Internal Server Error” indicates that there is something in your CGI script that the server does not like. There could be several reasons why you are receiving this error. Please review the following situations to see if one applies to you: Are you using the correct path to perl? The correct path to perl is: /usr/bin/perl. If you have the incorrect path, please correct it, save your changes and upload the revised script. Are your attributes for the cgi-bin directory set correctly? The correct attributes for the cgi-bin directory and the cgi script are both 755 (rwxr-xr-x). Please verify that these have been correctly set. Did you use a binary format to FTP the files? If so, please FTP your files again using the ASCII format. You should also ensure that you are using the correct permiss
the cgi script did not execute properly. There are several causes that can generate this error so https://help.directadmin.com/item.php?id=6 a few things would need to be checked. 1) check the /var/log/httpd/suexec_log. It contains any errors that would be as a result of not having correct http://unix.stackexchange.com/questions/123866/500internal-server-error-from-cgi-program permissions on the file. The file needs to be in a cgi-bin and must have the owner/group as the username who owns the site. If it's internal server owned by anyone else, it will not run. Also, the script must have execute permission. The most common chmod permission is 755. Go through all directories from the public_html down to the directory the script is in, and make sure they're all set to 755 (public_html can be 750 *only* if it internal server error has a group of apache). If the suexec_log only shows the script being run, then the cause may be with the script code itself. The easiest way to figure out script coding problems is to first run the script manually from an ssh prompt.cd /home/username/domains/domain.com/public_html/cgi-bin ./script.cgiOne common error is to use an incorrect interpreter. The 2 most common interpreters are:#!/usr/bin/perland#!/usr/local/bin/phpThis code must appear on the first line of the script. Somtimes a file is uploaded in windows format so the trailing newline (return) character is formed incorrectly and the file would need to be reuploaded in a different format. Other errors that would be generated when running the script manually from ssh would be missing perl modules, in which case you'll need to install them yourself. Cpan is the easiest method to install new perl modules, eg:perl -e shell -MCPAN install Bundle::DBD::mysqlorperl -MCPAN -e 'install Bundle::DBD::mysql' Related Helpfiles Running CGI script from any directory or via /~username/cgi-bin
