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


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.
