Most of the administration of an item is simple. Care needs to be taken when adding an item to ensure that the language is properly set. If this is not done, then your users may be confused, or not be presented with all the information.
The language that an item is stored in depends on which language version of the category it is added to. When you administer NEWS, be sure that your language selection is correct. NEWS will display a category in the user language if a version is available for that language. Otherwise, it will display the English version. The language setting for an item is based on the version of the category it is added to. For example.... You have created a category that has both an English and an Italian version.
If you set your language preference to English, then the English version of the category will be displayed, and if you add an item to that category entry, it will be added with an English language setting.
If you do not set your language preference to Italian and add an item to the Italian version of the category, then there will be no items to display for your Italian visitors, even though the category will be listed.
When your users display the category and items, those who have English as their language preference will see the category, and an item. Those who have Italian as their langugage preference will only see the category, but no items.
