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 how to fix 500 internal server error wordpress 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

Browse by products and services DV and VPS Hosting Grid Shared Hosting WordPress Hosting Legacy DV Hosting Applies to: All Service Types Difficulty: Medium Time Needed: 20 Tools Required: Plain text editor, FTP client Overview 500 Internal Server Error is https://mediatemple.net/community/products/dv/204644990/why-am-i-getting-a-500-internal-server-error-message a generic error message, given when no more specific message is suitable. 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 https://talk.plesk.com/threads/500-internal-server-error-when-trying-to-run-a-cgi-script.58121/ 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 internal server 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. CGI Script Guidelines When editing your CGI script, use a plain text editor - a program that saves the file as a 'text file' type. DO NOT use Wordpad that comes with Mic

Page 1 of 2 1 2 Next > MaRiOs Guest 0 Hello ppl, I need some more automatic things to put in plesk so I said I must begin learning perl to write my own scripts. I made a very easy one that just prints 2 words and i uploades to the cgi-bin area... (its the first time Im using the cgi-bin). so when i try to run the script i get : 500 Internal Server Error .... the link is : http://www.mariosmaravelias.info/cgi-bin/test.cgi what am I doing wrong? MaRiOs, Jul 23, 2005 #1 jamesyeeoc Guest 0 Could you post this script? Have you checked your log files? /var/log/messages /home/httpd/vhosts/mariosmaravelias.info/statistics/logs/access_log /home/httpd/vhosts/mariosmaravelias.info/statistics/logs/error_log jamesyeeoc, Jul 23, 2005 #2 MaRiOs Guest 0 #!/usr/bin/perl $name="Hello World"; print $name; i cantbe more simple than that MaRiOs, Jul 23, 2005 #3 jamesyeeoc Guest 0 And what about your log files, any errors or messages relating to this problem?? You should be seeing 'Premature end of script headers: test.cgi' in your error_log file Common solutions to this are: 1) Copy psa-suexec to suexec: cp /usr/sbin/psa-suexec /usr/sbin/suexecClick to expand... 2) Permissions: chmod -R 755 /home/httpd/vhosts/yourdomain.com/cgi-binClick to expand... 3) Ownership: chown -R ftpusername : psacln /home/httpd/vhosts/yourdomain.com/cgi-binClick to expand... (without the spaces around the colon : ) 4) File is ASCII: If you uploaded the file using FTP, it may have been uploaded in binary mode instead of ASCII, reupload it as ASCII. Then restart apache: service httpd restartClick to expand... In some cases, a whole server restart is necessary, not just apache restart. These have solved the same problem for countless others here on the forum. jamesyeeoc, Jul 23, 2005 #4 MaRiOs Guest 0 Ok I did these : 1)cp: `/usr/sbin/psa-suexec' and `/usr/sbin/suexec' are the same file 2)Done 3)Done 4) i didnt upload it , I loged in ssh and i made the file with nano editor. 5) ok i will try to restart it. about the error log files i dont see anythin about the script.. the only error i see is : [Mon Jul 25 12:29:05 2005] [warn] RSA server certificate CommonName (CN) `plesk' does NOT match server name!?
