  browser), goes through a process or rather a bike when communicating with the Web server equally illustrated below.
  #i Obtain an IP address from the IP name of the site (the site URL without the initial 'http://'). This lookup (conversion of IP name to IP address) is provided by domain name servers (DNSs).
  #2 Open an IP socket connection to that IP address.
  Write an HTTP information stream through that socket.
  #3Receive an HTTP data stream back from the Web server in response.
  This data stream contains condition codes, whose values are determined by the HTTP protocol, so Parse this data stream for status codes and other useful data.

  500 internal fault occurs in the final step above when the client receives an HTTP status lawmaking that information technology recognises equally 500 .

  Causes of 500 Internal Server Error

  The 500 Internal Server Error is a very full general HTTP status lawmaking that ways something has gone incorrect on the website's server but the server could not be more specific on what the exact trouble is.
  The causes of this error are many, but i will outline the major iii(three).

  1. File or Binder Permissions
     if you see in your cpanel error log, something similar [Sun Jun 05 12:03:22 2011] [error] [client 66.249.72.82] SoftException in Application.cpp:601: Directory "/home1/ examplec/public_html" is writeable by group, information technology means your account has a folder with an invalid permission set. To correct this, simply restore the permissions to from "777" to "755".
     if it is a file, chmod to "644", or if it cgi, chmod to "755".
  2. Bad code or syntaxes in your .htaccess
     When using .htaccess, if you do non enter the syntax correctly information technology can result in a Server 500 Error. Some mutual examples of what could cause an error is listed below.
     #1 FollowSymlinks
     [Sun Jun 05 12:07:10 2011] [alarm] [client 66.249.72.82] / home1/examplec/public_ html/.htaccess: Pick
     FollowSymlinks non immune hither In this example the error is simple to set; in the file specified, use a permitted directive–in this case use "SymlinksIfOwnerMatches" instead of "FollowSymlinks", or remove the line entirely.
     #ii Syntax Not Closed
     [Sun Jun 05 12:eleven:38 2011] [alert] [client 66.249.72.82] /home1/examplec/public_ html/.htaccess: /home1/examplec/public_ html/.htaccess:three: ExampleRule/ Module>
     You will discover syntax was not airtight. Again, the solution is to simply fix the syntax, or remove it. In this case, close the ending "" directive properly and put the rules on their ain line to resolve the trouble.

  In that location are few others that tin pb to corrupt .htacess file, only information technology delighting to know the description given by the error message is plenty to give yous an idea of what is wrong and how to fix information technology.

• Improperly configured php.ini
  This could be categorised into ForceType and Php_value.
  1. Force Type
     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 information technology 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 lot have a file called 'item' (like Nucleus uses for FancyURL'due south) and want it to be parsed by the server as php you utilise the following code in your .htaccess file:

     ForceType awarding/x-httpd-php

     However, because our servers employ phpsuexec this will result in an internal server error. To solve this you can just use SetHandler instead of ForceType, so your .htaccess-file becomes:

     SetHandler application/x-httpd-php php_value

  2. php_value
     On a server without phpsuexec information technology is possible to use the php_value statement in a .htaccess file to change the settings of php (really overwrite the settings from php.ini). On a sever with phpsuexec this will also result in a server error. To solve this you tin can apply a php.ini file which y'all put in the same folder as where you would have put your .htaccess file. In that php.ini file you can modify all the php values. Y'all only take to put the values you want to alter in that file. By example if yous want to fix the short_open_tag to Off yous would take used short_open_tag? = off in your .htaccess file. Using a php.ini file this results in:

     [ PHP ]
     short_open_tag = Off

• How To fix 500 Internal Server Error

  #i Open the Error Logs tool, located in the Logs section of the cPanel.
  #two Reload the web page that is causing the error.

  #4Search the error logs for your IP Address for whatsoever errors associated with information technology, your IP address is located at the top of the page.

  With the above washed, you may observe out that the problem may basically be
  * File or Folder Permissions
  * Bad code or syntaxes in your .htaccess
  * Improperly configured php.ini

  If that is the case click hither to read the solution equally stated in causes to a higher place.
