If you have not upgraded to that version please do so first.</p> <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> <li><dfn>application/config/smileys.php</dfn> (new file for 1.5)</li> <li><dfn>codeigniter/</dfn></li> <li><dfn>database/</dfn> (new folder for 1.5. Replaces the "drivers" folder)</li> <li><dfn>helpers/</dfn></li> <li><dfn>language/</dfn></li> <li><dfn>libraries/</dfn></li> <li><dfn>scaffolding/</dfn></li> </ul> <p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p> <h2>Step 2: Update your database.php file</h2> <p>Open your <dfn>application/config/database.php</dfn> file and add these new items:</p> <pre> $db['default']['cache_on'] = FALSE; $db['default']['cachedir'] = ''; </pre> <h2>Step 3: Update your config.php file</h2> <p>Open your <dfn>application/config/config.php</dfn> file and <kbd>ADD</kbd> these new items:</p> <pre> /* |-------------------------------------------------------------------------- | Class Extension Prefix |-------------------------------------------------------------------------- | | This item allows you to set the filename/classname prefix when extending | native libraries.
