hello guys
first i have to say the cms is not bad - i just look at it the first time
and have already problem
the multilanguage support

i found a docu where it says to add
Object::add_extension('SiteTree', 'Translatable');
in mysite/-config.php

i have done it and i get an error back

[User Error] Couldn't run query: SELECT Distinct Locale FROM SiteTree GROUP BY Locale Unknown column 'Locale' in 'field list'
GET /silver/admin/

Line 400 in C:\wamp\silver\sapphire\core\model\MySQLDatabase.php

can somebody explain to me in language which is understandable
i really dont understand the statements on the docu

thanks

Have you this setup?

Object::add_extension('SiteTree', 'Translatable');
i18n::enable();
Translatable::set_default_locale('it_IT');
