I upgraded wordpress to 2.0.5 yesterday, then I upgraded all my plugins. After that I noticed my feed republished itself in bloglines. However the feed entries were missing the Related Posts info that are part of a plugin I use. So I copied back my old wp-rss2.php. Now if I preview the feed I see all the correct info, but bloglines hasn’t updated my feed since yesterday and I even had a new entry. I also checked google reader and that also was missing the most recent entry. Ugh!!
Update: Well my feeds look like they are updating in various places now, but I had to deactivate my Feedburner Feed Replacement plugin.
