this is probably not it, but check if the feed url you past in has “feed:” at the beginning of it. if it does, remove the “feed:”.
if you’re lucky, that’s all it is.

I had the same problem, fixed the curly quote pasted in from Word (I’ll not do that again). Now, my comment RSS2 feed is declared invalid by the W3C Feed Validator, because “line 2, column 0: XML parsing error: <unknown>:2:0: xml declaration not at start of external entity “
Does this only mean that <?xml version=”1.0″ encoding=”UTF-8″?><!– generator=”wordpress/2.0.2″ –> is not on the first line?
If so, can WordPress be set to put it on the first line? or should I just forget it if there are no other errors?

Thank you. It was the Permalinks — deactivating the Custom Permalink plug-in, returning to default got everything working again.

I reverted an index.php to its default in the top level of my host directory, above WP blog directory to redirect to the blog’s index.php and the site displays. So, this issue is resolved — on to other problems.

my blog displays at this URL https://realnewyorkersknow.com/blog/index.php
but not at https://realnewyorkersknow.com/

thank you, that is now repaired – still no blog. template cacheing turned off, caches in browsers cleared. Must be an additional screw up. ideas?

Yes, of course, did it, thank you.
