Feed not syncing or delivering

[Lisa O'Brien]

I am new to this and not totally up on all the acronyms and verbage, so excuse my youthful ignorance here.

I have a new blog that I am using Google feedburner to deliver email subscriptions.

Google shows that my last post was several days ago. It doesn't seem to be syncing live with my site.

I tried to resync and got this error:

There is an issue that must be addressed with your source feed for the feed "lisa g. obrien"

Error getting URL: 404 - Not Found

my second error msg is "null" so it's not me alone whose feed stopped syncing since last few days.
