Upgrading 1.4.8 to 1.5+ prestashop ( client request )

[aaesis]

Hi All,

 

I was working on prestashop version 1.5 + and bought a themes in themeforest which can be run in 1.5 +. I worked 1.4.8 prestashop because client wants me to work with it and upgrade it to 1.5.4. I am having a problem in my database and ftp files. I compared the two version but its greatly not the same. So I transfer the files(1.4.8 version prestashop) to my localhost. And I got a lot of error.

 

PRESTASHOP VERSION 1.4.8

I changed the database of on setting.inc.php

 

define('__PS_BASE_URI__', '/');

define('_MEDIA_SERVER_1_', '');

define('_MEDIA_SERVER_2_', '');

define('_MEDIA_SERVER_3_', '');

define('_PS_CACHING_SYSTEM_', 'MCached');

define('_PS_CACHE_ENABLED_', '0');

define('_THEME_NAME_', 'apparel');

define('_DB_NAME_', 'prestashop_db');

define('_MYSQL_ENGINE_', 'MyISAM');

define('_DB_SERVER_', 'localhost');

define('_DB_USER_', 'root');

define('_DB_PREFIX_', 'ps_');

define('_DB_PASSWD_', '');

define('_DB_TYPE_', 'MySQL');

define('_COOKIE_KEY_', 'bRwxtVhG21zBzvmVPB1zecXhWuncBrXzgWqSEc4ShAMa9dUasT8Wb2xI');

define('_COOKIE_IV_', 'KmcBZZyf');

define('_PS_CREATION_DATE_', '2012-11-20');

define('_RIJNDAEL_KEY_', 'ppBpXhoROMH5xUCvP7BDgHejSneI6TmB');

define('_RIJNDAEL_IV_', 'Ykn7zVGZlMnMm/nbikfEvA==');

define('_PS_VERSION_', '1.4.8.3');

 

 

I changed also the sql

 

PS_SHOP_DOMAIN

PS_SHOP_DOMAIN_SSL

 

I changed the value to localhost and won't worked. I changed the value again to localhost/site_name and its working but when Viewing the site. I got error. Please check my attached file that was an error I encountered. CSS wont read and SQL error.
