Error message and feed not sending updates

[Cheryl P.]

For the last couple of weeks, my email subscribers complained that they weren't receiving my new posts. When I looked at my Feedburner account it looks like every time I have a new post there is a error message (503) that said that Google was unable to retrieve the feed but about a half hour behind that it said, Your feed is fine and carry on.

I went to my Blogger setting and changed my feed from full to short thinking that with 5 posts stacked up that had never been sent out, that maybe now the problem was  that I was over the 512K file size.

That worked. All my back posts went out.

Yesterday, I published a new blog and again, nothing.

I have my feed set for short but on the Feedburner site for my account it said "file too large"

After checking with the troublshooter directions I went so www.web-sniffer.net and it doesn't show that the file is too large. (of course, as I don't understand it, maybe I am reading it wrong)

When I looked at the Validate page on Feedburner it says" I have "use of unknown namespace and "self reference doesn't match document location"  Neither of those things I understand.

Behind those messages there are pages of yellow highlighted code that is just a jumple of words.  Like maybe the words used in the lables of old posts.

 

Also in the trouble shooting it says to add ?max-results=3 to the original feed line.  But on my account page it says NEVER change the original feed.  All of that makes me nervous.

 

I am attaching both the error messages and the validation info if that helps.
