I've been trying to fix feedburner for years with no success, I lost it several years ago, and have not been able to get it back. Google may say I am a beginner, because I do not spend all of my time helping others, cause there are so many loopholes, that I would spend all my time investigating and let my blog behind. I insist with due respect, that Google deserves,Blogger's team has the answer. I had ads in my blog but surprisingly one day appears in my dasboard that it wasn't approved. I deleted it. If I read all individual problems that I read on groups there are thousands of thousands and I'm short in the number.
Kind Regards,
