Standard Deviation Perl
usually a permissions error on your CGI script, which is easy to fix. 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 NOT use 0777 (a+rwx or -rwxrwxrwx). And your internal server error cgi python 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.) Now try to access the page in your browser again. If it works (you see "testing..." as its output

There are a number http://www.cyberciti.biz/tips/http-500-error-when-i-run-my-perl-script.html 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 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 server error 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 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 internal server error 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. See also: Using .htaccess rewrite rules Using .htaccess files PHP Coding Timing Out If your PHP script makes external network connections, the connections may time out. 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 external connections can increase both the performance of your website and decrease the chances of you receiving a "500 Internal Server Error." Syntax or coding errors in your CGI/Perl script If it is a web page ending in .cgi or .pl that is producing the error, check your script for errors. For detailed troubleshooting tips, please see: Troubleshooting CGI/PERL scripts.
