Upgrade error from 1.4.11.1 to 1.6.1.5, going mad!

[darvidc]

HELP, I'm going mad over this!!

 

I'm testing an upgrading (a manual upgrade) from 1.4.11.1 to 1.6.1.5 and am getting the same "28" xml error (<action result="fail" error="28"/> and I KNOW its meant to mean that I'm trying to upgrade to the version that is already installed BUT that is not the case!

 

Each time I run the upgrade, I delete everything and use an original 1.4 backup of the DataBase and files again. The important config file ("settings.inc.php") is then copied over with the other necessary 1.4 files again to the new upgrade folder holding the new 1.6 files, where it is then edited to point to the new test DataBase, disable cache, set base url and theme name etc. I don't touch the version setting "define('_PS_VERSION_', '1.4.11.1');", so it should reconise its an older/not the same version, during the upgrade!

 

So why DOSN'T IT, why do I get error 28 when its not true!!! ???  Any ideas anybody?

 

Things to note:

Running on a Debian 8, VPS

Permissions & Ownership on Files(644) & Dirs(755) are correct.

A completly new DataBase, with new name, is created with phpmyadmin, everytime I try.

These settings are put directly into the DB by an SQL statment, after import:

PS_SHOP_DOMAIN  "XX.YY.ZZ.SS" (not my real address )
PS_SHOP_DOMAIN_SSL ""
PS_SHOP_ENABLE "0"
PS_SSL_ENABLED "0"
_PS_BASE_URL_ "/"
 

I've also included my test "setting.inc.php" file as it is, placed in the upgrade folder, just before running the upgrade script.

 

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_', 'prestashop');
define('_DB_NAME_', 'ps1615');
define('_MYSQL_ENGINE_', 'MyISAM');
define('_DB_SERVER_', 'localhost');
define('_DB_USER_', 'root');
define('_DB_PREFIX_', 'amu_');
define('_DB_PASSWD_', 'XXXXXXXXXXX');
define('_DB_TYPE_', 'MySQL');
define('_COOKIE_KEY_', 'GA5tRnRO0ZbMmHdEIDkKQZwHLfQhHems0YrP71mnwII0EKFVmQSU1Aop');
define('_COOKIE_IV_', 'JQsZgUs1');
define('_PS_CREATION_DATE_', '2013-03-22');
define('_RIJNDAEL_KEY_', 'BS4ZBH5Y3DtEmJrQvUMIOdfP0xeP4dv9');
define('_RIJNDAEL_IV_', 'TkBqjTkzrvv7LGn6b653Cw==');
define('_PS_VERSION_', '1.4.11.1');

 

4 Days of trying now ... help would be really apprecated.

 

Thanks in advance
