prestashop 1.5.3.1 <action result="fail" error="28"/>

[Santscho]

I try to call upgrade.php and getting this error message:

 

<action result="fail" error="28"/>

 

After research, I found out that it means that my installation is already updated. But that is not possible.

 

 

Strange: The settings.inc.php shows PS_CREATION_DATE 2013-02-10
