How to update from v1.2 to v1.4

-------- IMPORTANT: REMEMBER TO DO A FULL-BACKUP (FTP/MYSQL) BEFORE STARTING ----------

Open your PHP My Admin and navigate to the database of the script, now click the SQL tab and run the following query:

ALTER TABLE users ADD salted VARCHAR(256) NOT NULL AFTER private;

If this was successfull too you can proceed to the next step:
---------------------------------------------------------------------------------------
Open /includes/config.php from your server

Find the following:

'search'		=> 'search',

Add after:

'recover'		=> 'recover',

It should look like this:

'search'		=> 'search',
'recover'		=> 'recover',

Save the file and upload over your current config.php file on your server.
---------------------------------------------------------------------------------------
Now the files from your server with these new ones:

/includes/functions.php
---------------------------------------------------------------------------------------
Now copy the following files on your server:
/sources/recover.php
/skin/recover/ (the entire folder)
/skin/welcome/form.html
---------------------------------------------------------------------------------------
Or you can do a clean-install.
