-<p>Before performing an update you should take your site offline by replacing the index.php file with a static one.</p>
-
-
-
-<h2>Step 1: Update your CodeIgniter files</h2>
-
-<p>Replace these files and directories in your "system" folder with the new versions:</p>
-
-<ul>
-
-<li><dfn>application/config/user_agents.php</dfn> (new file for 1.5)</li>

-

-$db['default']['cache_on'] = FALSE;
-$db['default']['cachedir'] = '';
-</pre>
-
-
-
-<h2>Step 3: Update your config.php file</h2>
-

-
-<pre>
-/*

-
-<p>If your <dfn>index.php</dfn> file has internal modifications, please add your modifications to the new file and use it.</p>
