Thank you Cricket,
The only url made by the feed burner you provided works. The url I posted on external blogs is
http://feeds.feedburner.com/blogspot/nReQ, but the url I was trying to post before "http://supreme-clothing.blogspot.com/feeds/posts/default" didn't work for me.
Now my latest blog looks OK, can you confirm that please. Thanks everyone for help.
Have a great day,
Peter
