[support] Block, regions and Site building

Hi all, I have this function into my theme's template.php file:

function mw_regions() { return array( 'left'=>t('Barra di sinistra MW'), 'right' => t('Barra di destra MW'), 'similar' => t('Regione per i similarterms MW'), 'header' => t('Header MW'), 'footer' => t('Footer MW'), 'articoli' => t('articoli'), 'articoliDanonperdere' => t("Articoli: danonperdere") ); }

Now, when I go into Home » Administer » Site building » Blocks and choice my theme name I can see only the first 6 regions and not the last (articoliDanonperdere) (that I have inserted 3 hours ago). I have tried to delete the cache, disable the cache, restart Firefox but nothing. The last region is not see.

Tnx.

M.
