I'm attempting to translate The Buffet Framework with the aid of Codestyling Localizazion. But in some way the theme simply does not use my translation.

Can there be something I didn't remember to think about? Any knowledge about that?

Thanks ahead of time.

Does your theme possess the line …

load_theme_textdomain(domain-name);

… in the functions.php? domain-name should suit your text domain.

Inside your wordpress directory, find wordpress-config.php then edit

define ('WPLANG', '');

for your language, example below:

define ('WPLANG', 'id_ID');
