<h1>Upgrading from 1.4.1 to 1.5.0</h1>
<p class="important"><strong>Note:</strong> The instructions on this page assume you are running version 1.4.1. 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. For more information please see the user guide:
|
| http://codeigniter.com/user_guide/general/core_classes.html
| http://codeigniter.com/user_guide/general/creating_libraries.html
|
*/
$config['subclass_prefix'] = 'MY_';
/*
|--------------------------------------------------------------------------
| Rewrite PHP Short Tags
|--------------------------------------------------------------------------
|
| If your PHP installation does not have short tag support enabled CI
| can rewrite the tags on-the-fly, enabling you to utilize that syntax
| in your view files. Options are TRUE or FALSE (boolean)
|
*/
$config['rewrite_short_tags'] = FALSE;
</pre>
<p>In that same file <kbd>REMOVE</kbd> this item:</p>
<pre>
/*
|--------------------------------------------------------------------------
| Enable/Disable Error Logging
|--------------------------------------------------------------------------
|
| If you would like errors or debug messages logged set this variable to
| TRUE (boolean). Note: You must set the file permissions on the "logs" folder
| such that it is writable.
|
*/
$config['log_errors'] = FALSE;
</pre>
<p>Error logging is now disabled simply by setting the threshold to zero.</p>
<h2>Step 4: Update your main index.php file</h2>
<p>If you are running a stock <dfn>index.php</dfn> file simply replace your version with the new one.</p>
<p>If your <dfn>index.php</dfn> file has internal modifications, please add your modifications to the new file and use it.</p>
<h2>Step 5: Update your user guide</h2>
<p>Please also replace your local copy of the user guide with the new version.</p>
