Problema instalare tema "child"

Buna,

Desi am urmat acest tutorial: http://codex.wordpress.org/Child_Themes#How_to_Create_a_Child_Theme pentru a crea o tema „child” peste tema „parent” primesc urmatoarea eroare in Dashboard:

„Broken Themes

The following themes are installed but incomplete. Themes must have a stylesheet and a template.

Name Description
Twenty Twelve Child The parent theme is missing. Please install the „Twenty Twelve” parent theme.”

Am urmat exact pasii din tutorial, am incercat chiar si cu o alta tema „parinte” dar la fel…

O solutie ?

Multumesc anticipat.
