Aggregator problem - posting an old story always at the top, can't get rid of it??? Sure this issue is local

Check and see if there is a "workable" date in the feed, I've seen this happen when the feeds have no date, today, "unreadable" format, or a date in an "unexpected" place.

A simple workaround is to create 2 categories, one for these types of feeds and another to display the "main" aggregator page (dateless feeds excluded).
Display the "main" category as the main aggregator feed, and move offending entries as needed between the categories.
You can then re-categorize the "dateless" feed items manually, with a trigger/action combo, in the theme (see http://drupal.org/node/109568 for an indication how) or with a module that you make for this purpose.

MYCON,

can you post the URL of the problematic feed, with URL of the offending story?

That would really simplify debugging the problem!

Never mind.

PS, I was just going to say that.
The example was http://www.phpbuilder.com/rss_feed.php?type=articles&limit=20

@Bobby1290:

The reason for that is the items in that RSS feed have no dates attached, so they have to default to the time the feed was aggregated. Here is an example item which demonstrates:

<item>
  <title>The ABC's of PHP - Part 10 - The Final Installment</title>
  <link>http://www.phpbuilder.com/columns/peter_shaw06012009.php3</link>
  <description>In this last installment in our series Peter Shaw ties it all together and shows you how to put the  ...</description>
</item>

Thanks, I understand.

PS, I was wondering if there was an easy way to save the dates of the older items, that already had a date (previous aggregation) in my drupal database.
Actually what I would want is to simply not overwrite already available feed items. but this moy not be easy as the whole feed seems to be "node" like.

In this particular case 20 items pop up if nothing is done.
