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 500 internal server error apache php 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.

Go to your FTP client, or your website file manager, and highlight or right-click on the CGI script. Then choose Properties, or Permissions, or "Chmod", and set it to world-executable: that's 0755, or a+rx, or -rwxr-xr-x. Do https://encodable.com/internal_server_error/ NOT use 0777 (a+rwx or -rwxrwxrwx). And your cgi-bin directory itself should also be 0755, not 0777. The long answer: when running a Perl CGI script like FileChucker or UserBase, you may see the "Internal Server Error" message in your browser. The message will usually also say something like "please check the server's error-log for more information." You should do that -- the message printed to the error log will often tell you exactly what the problem is. The Apache error log, for example, is often located at /var/log/apache/error_log or /var/log/apache2/error_log (or sometimes "error.log"). If you don't have access to the error log, the next simplest thing to do is to make a backup copy of the script, then open the original and delete all of its contents, and add just these 3 lines to the file: #!/usr/bin/perl print "Content-type: text/plain\n\n"; print "testing...\n"; (Note: if the server is a Windows system, then replace the first line above with either #!perl or #!c:\path\to\perl.exe.)
