RSS feed link goes to white text page

Hello everyone. My first post here. I have done my first WP custom theme which I developed locally then moved to live site.

All seems to be well except that the rss feed links to a white page of text. If I click the rss feed on local host it goes to the typical “choose your reader” etc. page, but not on live site?

The site can be seen at https://www.2golfguys.com

Any help greatly appreciated!
