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 internal server error cgi-bin apache 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

Cgi Script Internal Server Error
Internal Server Error is a generic error message, given when no more specific message internal server error php is suitable. There are a number of causes for a 500 Internal Server Error to display in a web browser. Below is a internal server error apache 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 http://www.thesitewizard.com/archive/servererror.shtml 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 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 https://mediatemple.net/community/products/dv/204644990/why-am-i-getting-a-500-internal-server-error-message 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. 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.

be caused by many things, including but not limited to invalid permissions, invalid ownership, bad lines in your php.ini or .htaccess file, invalid requests in the script, and others not mentioned here. Typically this is not a problem with the server itself, and can be most often resolved by modifying something in your site's configuration. Please check the Error Logs in cPanel for specific information. Example of Server 500 Error Bad permissions, Writable by group Bad .htaccess, Invalid code, command, or syntax Improperly configured php.ini Example of Server 500 Error A Server 500 error will generally look something like this:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, webmaster@example.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.
Bad permissions, Writable by group A bad permissions error may look something like this: [Sun Jun 05 12:03:22 2012] [error] [client 66.249.72.82] SoftException in Application.cpp:601: Directory "/home/exampleuser/public_html" is writeable by group In this instance the folder had permissions for a folder set too high. To correct this, the permissions need to be changed from "777" to "755". Directories and folders should be 755. Executable scripts within the cgi-bin folder must be 755. Images, media, and text files like HTML should be 644. Files - 644 CGI Scripts - 755 Directories - 755 You can modify permissions with the File Manager, located in the "Files" category of the cPanel, an FTP client, or using the chmod command in SSH/Bash. Bad .htaccess, Invalid code, command, or syntax In the .htaccess file ("dot htaccess"), you may have added lines that are either worded badly or conflicting. The best way to troubleshoot this is comment out the lines in the .htaccess. You can comment out a line in the .htaccess by adding # to the beginning. You are wise to save an orig
