For the purposes of this article, I am assuming that your CGI script is a Perl script, by apache internal server error log 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 ASCI

This document will be an introduction to setting up CGI on your Apache web server, and getting started writing CGI programs. Configuring Apache to permit CGI In order to get your CGI programs to work properly, you'll need to have https://httpd.apache.org/docs/2.4/howto/cgi.html Apache configured to permit CGI execution. There are several ways to do this. Note: If Apache has been built with shared module support you need to ensure that the module is loaded; in your httpd.conf you need to make sure the LoadModule directive has not been commented out. A correctly configured directive may look like this: LoadModule cgid_module modules/mod_cgid.so On Windows, or using a non-threaded MPM like prefork, A correctly configured directive may look like this: LoadModule cgi_module modules/mod_cgi.so ScriptAlias The ScriptAlias directive tells Apache that a particular directory is set aside for CGI programs. Apache will assume that every file in this directory is a CGI program, and will attempt to execute it, when that particular resource is requested by a client. The ScriptAlias directive looks like: ScriptAlias "/cgi-bin/" "/usr/local/apache2/cgi-bin/" The example shown is from your default httpd.conf configuration file, if you installed Apache in the default location.

There are a number of causes for a 500 Internal Server Error to display in a web browser. Below is a sample error message. This article provides information on the most common causes. Check the Error server error Logs! With any error message, particularly one as broad as the 500 Internal Server Error, you will first want to check any Apache and PHP error logs for your server. These logs can provide valuable context related to any code failures or other potential causes of a site failure. For information on where to find the logs for your server, please see: Where are internal server error the access_log and error_log for my server? Error with an .htaccess file If you are using a .htaccess on your site, it may be interfering with the web page you are trying to load into your browser. Please double check the .htaccess configuration. Any syntax errors will cause a 500 Internal Server Error message to be displayed instead of your website. To confirm whether a misconfiguration .htaccess is the cause of the 500 Internal Server error, either remove or rename the .htaccess file temporarily and then try to reload the page.

If too many connections are attempted and time out, this will cause a "500 Internal Server Error." To prevent these time outs and errors, you'll want to make sure that PHP scripts be coded with some timeout rules. Typically, however, catching a timeout error when connecting to a database or externally to remote resources (example: RSS feeds) are difficult. They, in effect, freeze the script from continuing to run. Removing any e
