Nevermind what i said before, I figured it out.
If you pass the following SQL query to the database it should correct the pages/posts damage.
In SQL:
UPDATE wp_posts
SET post_type = ‘page’
WHERE menu_order<>’0′
In PHP:
$sql = ‘UPDATE wp_posts
‘
. ‘ SET post_type = \’page\”
. ‘ WHERE menu_order<>\’0\”
. ‘ ‘;
