I'm new to Thematic, but I have been an avid WordPress user for years.
I just changed my blog to run with the Sophia child theme. I noticed immediately a large drop in my Feedburner stats. Some other feed aggregators are also claiming they can no longer see my blog, even though Feedburner sees it. When validating the feed for my site, it shows no support for Atom feeds. When I checked the page source, sure enough, no code exists for handling Atom calls. It appears that Thematic and Sophia lack a line of code for generating Atom feeds.
What I can't figure out is where to add code (or precisely how it must be done within Thematic/Sophia) to generate an Atom feed. Also, why is an Atom feed not automatically generated by Thematic?
Thanks in advance for the help!
