Manual Update 1.5.3.1 to 1.5.4 failed "Error 34 Update_customer_default_group failed"

[gorllzz]

Hello people,

 

I'm trying to do the manual upgrade from version 1.5.3.1 to 1.5.4 but I´m facing the following problem:

<action result="fail" error="34"><request result="ok" sqlfile="1.5.4.0"><sqlQuery>SET NAMES 'utf8'</sqlQuery></request><request result="fail" sqlfile="1.5.4.0"><sqlQuery>/* PHP:update_customer_default_group(); */</sqlQuery><phpMsgError></phpMsgError><phpNumberError></phpNumberError>

 

The other queries are being executed without error. I checked the php file and it's the same as the one shown here:https://raw.github.com/PrestaShop/PrestaShop/d4bf96b387691449343dcd565c5795eb86135e2e/install-dev/upgrade/php/update_customer_default_group.php

 

Anybody can give me a hand here??

 

Thanks in advance!
