Just putting this note here in case somebody is scratching their head. –Tom Hundt Jul 8 at 18:29 add a comment| 7 Answers 7 active oldest votes up vote 4 down vote accepted The error log usually has the (more) specific error. often it will be permissions denied or even an interpreter that can't be found. This means the fault almost always lies with your script. e.g you uploaded a perl script but didnt give it execute permissions? or perhaps it was corrupted in a linux environment if you write the script in windows and then upload it to the server without the line endings being converted you will get this error. in perl if you forget print "content-type: text/html\r\n\r\n"; you will get this error There are many reasons for it. so please first check your error log and then provide some more information. The default error log is often in /var/log/httpd/error_log or /var/log/apache2/error.log. The reason you look at the default error logs (as indicated above) is because errors don't always get posted into the custom error log as defined in the virtual host. Assumes linux and not necessarily perl share|improve this answer edited Mar 2 at 0:05

October 24, 2006 in Apache, lighttpd, TroubleshootingYou get "500 - Internal server error" error message when a user tries to access your Apache or Lighttpd based dynamic php application (such as forum or blog software).
Generally, to solve this problem you need to take help of log files located at following location: => /var/log/message => /var/log/httpd/error_logs (/var/log/lighttpd/error_log or /var/log/httpd/error_log)So you may be wondering why your PHP script throws an Internal Server Error 500.This error only occurs because of web server software. However after looking through logs you may not find many details. This problem may be caused by:A malformed php cgi scriptAn invalid directive in an .htaccess or other config fileLimitation imposed by file system and server software (for example php log file size set to 10Mb)Missing php.ini (or cannot read php.ini file)In most case it is an invalid .htaccess directive. However recently I came across a web server w/o /etc/php.ini file. A long time ago I setup this server )Apache chrooted jail). So you need to maintain two files one outside jail and another inside jail: => /etc/php.ini => /chroot/etc/php.ini <-- this file was missing Many scripts open this file on fly to get correct configuration directives. If this file not found you get error 500. It took some time to figure out this problem. Finally strace helped me out to debug this problem.
