title: Yii 1.1.7 - cannot find gii page
body: <p>I want to use Gii in Yii.  My protected/config/main.php for my first webapp has this part uncommented, as instructed in the Yii documentation to enable Gii (123.45.67.123 is my public IP address from the computer I am trying to access):</p>
  
  <pre><code>'modules'=&gt;array(
              // uncomment the following to enable the Gii tool
              'gii'=&gt;array(
                      'class'=&gt;'system.gii.GiiModule',
                      'password'=&gt;'123456',
                      // If removed, Gii defaults to localhost only. Edit carefully to taste.
                      'ipFilters'=&gt;array('123.45.67.123','127.0.0.1','::1'),
              ),
      ),
  </code></pre>
  
  <p>I also have the urlManager enabled in my protected/config/main.php by uncommenting the below:</p>
  
  <pre><code>// uncomment the following to enable URLs in path-format
              'urlManager'=&gt;array(
                      'urlFormat'=&gt;'path',
                      'rules'=&gt;array(
                              '&lt;controller:\w+&gt;/&lt;id:\d+&gt;'=&gt;'&lt;controller&gt;/view',
                              '&lt;controller:\w+&gt;/&lt;action:\w+&gt;/&lt;id:\d+&gt;'=&gt;'&lt;controller&gt;/&lt;action&gt;',
                              '&lt;controller:\w+&gt;/&lt;action:\w+&gt;'=&gt;'&lt;controller&gt;/&lt;action&gt;',
                      ),
              ),
  </code></pre>
  
  <p>When I go to my Yii site, for example, www.example.org, the basic Yii page is loaded fine.  When I do www.example.org/gii, I get a 404. When I go to www.example.org/index.php?r=gii, I get a 404.  Why is my Gii page not found?  I am using CentOS 5.6.</p>
