You upgrade it from the old news version?
Are you using a custom template (clone)?
If all yes,
Did you run the upgrade.php script:
http://www.domain.com/modules/news/admin/upgrade.phpIf that didn't work out, might be your custom template.
Admin > System Menu > Templates > News
Inside the news templates
only delete them all and them go back up one level you will see a red make with the "generate" word.
Click that then you should be fine.
