   I am posting the headlines of other blogs on my WP blog via RSS. For the last week, 4 of the feeds are updating fine, but two seem stuck -- even though the source feeds have information from today, my WP blog still has information cached from 10 days ago.

   Is there a way to "flush" the RSS cache on my blog? I have access to PHPMyAdmin, so is there a way to run a query, and if so what should I do?

   This is the code I'm using to grab RSS feeds:

   <?php
   require_once(ABSPATH . WPINC . '/rss-functions.php');
   $rss = fetch_rss('http://LINKTOFEED');
   echo '<!--Start-->';
   for($i=0;$i<4;$i++) {
   $item=$rss->items[$i];
   echo '<p><a href="'.$item['link'].'">'.$item
   ['title'].'</a></p>';
   }
   echo '<!--RSS FEED STOPS HERE-->';
   ?>

   Sorry to bump after 2 days, but this is rather urgent and I can't find RSS flushing info elsewhere -- I'm sure others have had similar problems, right?

   In the wordpress options table, look for rows that have a key of rss_big-bunch-of-gibberish-here. Those are the cache entries. Delete those rows.

   Note, only delete the rows with the gibberish looking keys. Don't delete rss_anything_else.

   So is there no setting that can be passed in for affecting the cache lifetime/length? I'd like to do something like 30 minutes, but it seems to be caching for more than 12 hours (and obviously I don't want to be digging around in mysql tables all the time).

   Thanks.

   you can set the time to cache feeds, its just Magpie.

   wp-includes/rss.php

   if ( !defined('MAGPIE_CACHE_AGE') ) {
   		define('MAGPIE_CACHE_AGE', 60*60); // one hour
   	}

   change as you like.

   Ah, turns out it wasn't fetch_rss causing this, but Twitter changed their atom feeds to run through a password protected bloglines account. But vanilla RSS still works. Thanks anyway whoo good to know.
