Permalink Feed Conflict
Recently, as of WordPress 3.01, we’re starting to see a problem where some users can’t get to their podcast feed. If they use the /feed/podcast format the url takes them to the first post, page, or category with ‘podcast‘ as the first part of the url.
If this is happenings to you, you can use the non-permalink format:
http://mydomain.com/feed/podcast (is taking you to another page)
We’re looking into what might be causing this.
