Problem Resolution Set correct permissions Check .htaccess directives Related Articles Problem Visitors to your web site receive "500 Internal Server Error" messages when they access a page that uses PHP. Resolution Almost all of our servers run PHP as a CGI binary. One https://www.a2hosting.com/kb/developer-corner/php/500-internal-server-error-while-running-php of the side effects of running PHP as a CGI binary is that internal server errors can occur if the permissions on files and directories are set incorrectly. Internal server errors can also occur if there are certain PHP directives defined in an .htaccess file. If your web site is experiencing internal server errors, the first thing you should do is check the server logs. The server logs provide valuable information about which files are causing the errors, and potential causes. If you have a shared hosting account, you can view your web site's error logs in cPanel. If you have a VPS or dedicated server, you can view your web site's log files directly at the following paths: /usr/local/apache/logs/error_log /usr/local/apache/logs/suphp_log Set correct permissions If permission settings are causing internal server errors, you may see entries in the server logs similar to any of the following lines: SoftException in Application.cpp:357: UID of script "/home/username/public_html/.htaccess" is smaller than min_uid SoftException in AppOctober 24, 2006inApache,lighttpd,TroubleshootingYou get "500 - Internal server error" error message when a user tries to access your Apache or Lighttpd based dynamic http://www.cyberciti.biz/tips/http-error-500-internal-server-for-php-pages-and-solution.html php application (such as forum or blog software).
Generally, to solve this https://my.hostmonster.com/cgi/help/123 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 internal server looking through logs you may not find many details. This problem may be caused by:A malformed php cgi script An 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 internal server error 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.

When a php script requires write access to a file or directory (like Nucleus does for the 'media'-directory if you want to be able to upload pictures etc), you have to chmod that directory (or file) to 777 (or 666 for files) on most servers. This gives world write access to this folder (file). This is because on most servers apache (and php) runs as user 'nobody'. Although giving world write access will make it possible to use the script, it also means a security hole, which can be used by hackers and other riff-raff. To avoid this security hole we run phpsuexec on our servers. Using phpsuexec, php runs under your own username on the server. This removes the necessity to make files and folders world writable. Instead you can just use 755 for folders (the default) and 644 for files (also the default). Using phpsuexec may have some consequences. Specific statements in your .htaccess file may result in an error 500 (internal server error). So here are two possible problems, and how to solve them: ForceType When you are using files with (or without) an extension different then the normal extension for that filetype you can use ForceType in your .htaccess file to make it clear to the server how to handle that file (or all the files in the folder) (this works on servers without phpsuexec). An example: When you have a file called 'item' (like Nucleus uses for FancyURL's) and want it to be parsed by the server as php you use the following code in your .htaccess file: However, because our servers use phpsuexec this will result in an internal server error. To solve this you can simply use SetHandler instead of ForceType, so your .htaccess-file becomes: SetHandler application/x-httpd-php php_value On a server without phpsuexec it is possible to use the php_value statement in a .htaccess file to change the settings of php (actually overwrite the settings from php.ini). On a sever with phpsuexec this will also result in a server error. To solve this you can use a php.ini file which you put in the same folder as where you would have put your .htaccess file. In that php.ini file you can change all the php values. You only have to put the values you want to modify in that file. By example if you want to set the short_open_tag to Off you would have used short_open_tag? = off in your .htaccess file. Using a php.ini file this results in: [PHP] short_open_tag = Off Knowledgebase Article 127,593 views
