this should solve your problem:
replace this code (about line 135 in /modules/news/view.php)
<?php
// Query posts (for this page)
$query_posts = $database->query("SELECT * FROM ".TABLE_PREFIX."mod_news_posts
WHERE section_id = '$section_id' AND active = '1' AND title != ''$query_extra
AND (published_when = '0' OR published_when <= $t) AND (published_until = 0 OR published_until >= $t)
ORDER BY position DESC".$limit_sql);
?>
with the code below:
<?php
// Query posts (for this page)
$query_posts = $database->query("SELECT * FROM ".TABLE_PREFIX."mod_news_posts
WHERE section_id = '$section_id' AND active = '1' AND title != ''$query_extra
AND (published_when = '0' OR published_when <= $t) AND (published_until = 0 OR published_until >= $t)
ORDER BY posted_when DESC".$limit_sql);
?>
