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:
- 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 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
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.
