Upgrading from 1.5.3 to 1.5.4

Before performing an update you should take your site offline by replacing the index.php file with a static one.

Step 1: Update your CodeIgniter files

Replace these files and directories in your "system" folder with the new versions:

system/application/config/mimes.php
system/codeigniter
system/database
system/helpers
system/libraries
system/plugins

Note: If you have any custom developed files in these folders please make copies of them first.

Step 2: Add charset to your config.php

Add the following to system/application/config/config.php

/*

	|--------------------------------------------------------------------------

	| Default Character Set

	|--------------------------------------------------------------------------

	|

	| This determines which character set is used by default in various methods

	| that require a character set to be provided.

	|

	*/

	$config['charset'] = "UTF-8";

Step 3: Autoloading language files

If you want to autoload any language files, add this line to system/application/config/autoload.php

$autoload['language'] = array();

Step 4: Update your user guide

Please also replace your local copy of the user guide with the new version.
