Evangoer tells the truth,
I see this error on all of the feeds, but it seems like they all are working
fine, if anyone has problems with feeds and thinks this issue is the cause,
please reply with the issue; this way we will know if there are issues that
caused by this error and we could ask and follow it here to find out what is the
fix.

Here is another question: When we will see these results in the search results?
Is there any extra steps to take? I have not seen any of the account's results
in Yahoo! search results.

Thanks Evangoer for the good news.

Bottom line: ignore the bogus errors, Site Explorer feed submissions are still
open for business. Thanks for your patience!
