Still experiencing the problems with some feeds not being picked up, or suddenly disappearing, as described here:
but have also noticed another strange thing:
Some posts from some feeds appear in duplicates.
You can see an illustration here:
This is a screen shot of the page where I use the short-code to display the latest posts:
You can see that one post from the feed called "Lessrof" even appears in triplicate ("Pecharmant vs Saint-Emilion Grand Cru").
The feed from that blog only contains one entry for that post.
And one of my own blogs, "BKWine Blogg (svenska)+" also appears in duplicate: "Strukturen framfor allt". (The "+" in the feed name is there to make it appear in the list. It had disappeared since yesterday, as described in my other error report).
It also seems that after a while at least some of these duplicates disappear.
