Unable to Cross-Post -- Error: not found

I think I have cross-posting set up correctly for my blog, but nothing shows up on the accounts I’ve connected (Mastodon and Tumblr). Under the url for my feed it says Error: not found. Could this be the problem? How do I fix that?

This should be fixed now. Seems to have been a bug with the uppercase “E” in your feed URL. Sorry about that!

Works now. Thanks so much for fixing that!
