Upgrading from 1.4.1 to 1.5.0

Note: 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.

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

Step 1: Update your Code Igniter files

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

application/config/user_agents.php (new file for 1.5)
codeigniter/
database/ (new folder for 1.5. Replaces the "drivers" folder)
helpers/
language/
libraries/
scaffolding/

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

Step 2: Update your database.php file

Open your application/config/database.php file and add these new items:

$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';

Step 2: Update your config.php file

Open your application/config/config.php file and ADD this new item:

/*
|--------------------------------------------------------------------------
| 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://www.codeigniter.com/user_guide/general/core_classes.html
| http://www.codeigniter.com/user_guide/general/creating_libraries.html
|
*/
$config['subclass_prefix'] = 'MY_';

In that same file REMOVE this item:

/*
|--------------------------------------------------------------------------
| 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;

Error logging is now disabled simply by setting the threshold to zero.

Step 4: Update your main index.php file

If you are running a stock index.php file simply replace your version with the new one. If you are running one with internal modifications, open it and add this line of code near the bottom:

define('FCPATH', __FILE__);

Step 5: Update your user guide
