Podcasts stopped posting in iTunes mysteriously

[Jann]

For some reason, our stream of weekly podcasts stopped posting in iTunes about 6 weeks ago. From the image I am including, you might notice that the podcasts posted every week in July, but then they stopped.

I can't figure out what to do next. I am still adding all my weekly podcasts in Poderator and publishing my .xml file, but the podcasts are not appearing in iTunes for our normal podcast subscribers.
