# Upgrading From Beta 1.0 to Beta 1.1

To upgrade to Beta 1.1 please perform the following steps:

## Step 1: Replace your index file

Replace your main `index.php` file with the new index.php file. Note: If you have renamed your "system" folder you will need to edit this info in the new file.

## Step 2: Relocate your config folder

This version of CodeIgniter now permits multiple sets of "applications" to all share a common set of backend files. In order to enable each application to have its own configuration values, the `config` directory must now reside inside of your application folder, so please move it there.

## Step 3: Replace directories

Replace the following directories with the new versions:

- drivers
- helpers
- init
- libraries
- scaffolding

## Step 4: Add the calendar language file

There is a new language file corresponding to the new calendaring class which must be added to your language folder. Add the following item to your version: language/english/calendar_lang.php

## Step 5: Edit your config file

The original `application/config/config.php` file has a typo in it Open the file and look for the items related to cookies:

`$conf['cookie_prefix'] = "";
$conf['cookie_domain'] = "";
$conf['cookie_path'] = "/";`

Change the array name from `$conf` to `$config`, like this:

`$config['cookie_prefix'] = "";
$config['cookie_domain'] = "";
$config['cookie_path'] = "/";`

Lastly, add the following new item to the config file (and edit the option if needed):

`
/*
|------------------------------------------------
| URI PROTOCOL
|------------------------------------------------
|
| This item determines which server global
| should be used to retrieve the URI string. The
| default setting of "auto" works for most servers.
| If your links do not seem to work, try one of
| the other delicious flavors:
|
| 'auto' Default - auto detects
| 'path_info' Uses the PATH_INFO
| 'query_string' Uses the QUERY_STRING
*/
$config['uri_protocol'] = "auto";`
