It turned out that I had everything with the quick subscription icon (in the address bar), but the big orange button in the sidebar referred to the feed a la profithunter. ru / feed.
If you subscribe to my feed using this button, I would be very grateful if you subscribe again (I changed the link in the button to the feed from FeedBurner.)
Updated: I figured out the topic, everything I have with a subscription is ok. I apologize 🙂
