62
63<h2>Step 1: Update your CodeIgniter files</h2>
64
65<p>Replace all files and directories in your "system" folder and replace your index.php file. If any modifications were made to your index.php they will need to be made fresh in this new one.</p>
66
67<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>

Greg Aker3a746652011-04-19 10:59:47 -0500[diff] [blame]70
71<p>If you are running a stock <dfn>index.php</dfn> file simply replace your version with the new one.</p>
72
73<p>If your <dfn>index.php</dfn> file has internal modifications, please add your modifications to the new file and use it.</p>

Greg Aker3a746652011-04-19 10:59:47 -0500[diff] [blame]76
77<p>This config file has been updated to contain more user agent types, please copy it to <kbd>application/config/user_agents.php</kbd>.</p>

Greg Akerf092fdf2011-08-20 16:53:52 -0500[diff] [blame]82<h2>Step 5: Remove APPPATH.'third_party' from autoload.php</h2>
Greg Aker44885382011-04-19 15:28:40 -0500[diff] [blame]83
Bo-Yi Wuc51a4352011-08-23 10:40:39 +0800[diff] [blame]84<p>Open application/config/autoload.php, and look for the following:</p>
Greg Aker44885382011-04-19 15:28:40 -0500[diff] [blame]85
86<code>$autoload['packages'] = array(APPPATH.'third_party');</code>
87
88<p>If you have not chosen to load any additional packages, that line can be changed to:</p>
89<code>$autoload['packages'] = array();</code>
90
91<p>Which should provide for nominal performance gains if not autoloading packages.</p>
