FYI: hr hasn't been finished yet: http://i18n.osticket.com/project/osticket-official/hrAs for setting the default.. it should have been done on Install.. but I can't see it in mine! maybe it doesn't.. dunno. You could try adding the setting "system_language", like:INSERT INTO `ost_config` (`id`, `namespace`, `key`, `value`, `updated`) VALUES (NULL, 'core', 'system_language', 'hr_HR', CURRENT_TIMESTAMP);Which should override the default: 'system_language' => 'en_US',
