Lines are extracted from my /etc/httpd/conf/httpd.conf file that are possibly related:

LoadModule rewrite_module modules/mod_rewrite.so
DocumentRoot "/var/www/html"
<Directory "/var/www/html">
    Options Includes ExecCGI FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
</Directory>


Also from my /etc/php.ini file:

include_path = ".:/usr/lib/php"


In the /var/www/html/.htaccess file are only these lines:

RewriteEngine on
RewriteRule !\.(js|ico|gif|jpg|png|css)$ index.php


The following lines have been added to top of the /var/www/html/index.php file:

<?php
require_once 'Zend/Controller/Front.php';
Zend_Controller_Front::run('/var/www/application/controllers');
?>
