Error Updating From 1.3.1.1 To 1.4.10

[Okidoki]

I´m trying update prestahop from 1.3.1.1.to 1.4.10 in localhost

Every time, in the 3º step of installation I get this error:

Error during install/upgrade: ( ! ) Notice: Use of undefined constant _PS_CACHE_ENABLED_ - assumed '_PS_CACHE_ENABLED_' in C:\wamp\www\ps10\classes\MySQL.php on line 147 Call Stack #TimeMemoryFunctionLocation 10.0014166608{main}( )..\model.php:0 20.0143470064ConfigurationCore::loadConfiguration( )..\model.php:62 30.0293587176MySQLCore->ExecuteS( )..\Configuration.php:324

 

You may have to:

• Fix the error(s) displayed
  
• Put your database backup
  
• Modify the file settings.inc.php to put the old version for the line with _PS_VERSION_
  
• Restart the upgrade process from the begining

Please, help

Before you start the upgrade, add the following lines in config/settings.inc.php file

define('_PS_CACHING_SYSTEM_', 'MCached');
define('_PS_CACHE_ENABLED_', '0');
