For the last few months I've been seeing something really weird. Sporadically and no for reason that I can understand, random URLs on our WP site will show a single comment RSS feed instead of the content itself. This could be page 2 of the home page, a single post page, a tag page, etc.
The issue appears and within a few minutes, disappears. However, it doesn't appear for all users. A user can be experiencing the issue, while other users see the site as it should be.
Any idea what might be causing it?
