RSS Feed not showing all threads

[cisoprogressivo]

I've enabled RSS feed in my Vbulletin forum, but in some forum not all the threads are showing.
Example.
Forum:
http://www.androidworld.it/forum/samsung-galaxy-s4-i9500-489/
Feed:
http://www.androidworld.it/forum/external.php?type=RSS2&forumids=489

The three threads were all started over a week ago. The RSS Feed it going to show more recent threads than those. Check your AdminCP > Settings > Options > External Data Provider settings.

Ok,
thank you very much. I thought that it was based on "last reply" date and not on the "creation" date.
