Thanks for the reply. I got it to work. There was a typo in the tutorial I was following. now when I try to go to any other page I get a 404 error. I found an article that mentions the htaccess file and changing it from this:

  <IfModule mod_rewrite.c>
      <IfModule mod_negotiation.c>
          Options -MultiViews
      </IfModule>

      RewriteEngine On

      # Redirect Trailing Slashes...
      RewriteRule ^(.*)/$ /$1 [L,R=301]

      # Handle Front Controller...
      RewriteCond %{REQUEST_FILENAME} !-d
      RewriteCond %{REQUEST_FILENAME} !-f
      RewriteRule ^ index.php [L]
  </IfModule>
  # Use PHP54 as default
  AddHandler application/x-httpd-php54 .php
  <IfModule mod_suphp.c>
      suPHP_ConfigPath /opt/php54/lib
  </IfModule>

  to this

  <IfModule mod_rewrite.c>
      # <IfModule mod_negotiation.c>
          Options -MultiViews
      # </IfModule>

      RewriteEngine On

      # Redirect Trailing Slashes...
      RewriteRule ^(.*)/$ /$1 [L,R=301]

      # Handle Front Controller...
      RewriteCond %{REQUEST_FILENAME} !-d
      RewriteCond %{REQUEST_FILENAME} !-f
      RewriteRule ^ /index.php [L]
  </IfModule>

the difference is in the RewriteRule. There is a '/' just before index.php. I tried that but it didn't work for me. In his article it was his solution
