RSS Posts Feed Empty

version 2.2.1

A brand new install, https://www.saltwaterfuel.net/ the RSS feed https://www.saltwaterfuel.net/feed is blank although the comment feed is okay.

I tried replacing the feed and rss php files with ones from a site that was working and none of the other threads on the same topic seem to offer any solutions that worked.

Any ideas or suggestions on what I can try?

thanks a lot,

Jon
