Invalid feed re-direct – feed not available

When I enter my feed name at https://livingveniceblog.com/feed, I am redirected to https://feeds.feedburner.com/LivingVeniceandBeyond, where I get an access error. So, none of the feeds work on the site. I deleted the original feed address on Feedburner, and when I try to create it, I get a circular reference error.

I can’t pin down where this name value is coming from. I’ve read through the documentation, which is just beyond me (I do better with schematics, unfortunately). I have another blog that works fine, even without the feedburner plugin or .htmaccess modification – https://vogadoc.org. Don’t know what the difference is, but I would like to understand this better and have them both work the same way.

Thanks for any assistance…as always.
