RSS Feed showing up as a fiename, not the actual feed

Your feed is here, https://pramainstitute.org/feed

You should try to clean up these errors, https://validator.w3.org/check?verbose=1&uri=http%3a%2f%2fpramainstitute.org%2f

No, that’s the wrong feed. That’s just all the new stuff up on the website. I’m creating a custom feed, which is in the /feeds folder. In fact, I can’t even find a /feed folder on our server.

Hmmmmm yeah, helps me understand it better. However, I’m not clear on how to customize my feed. For example, there’s some items I don’t want to include, and I want a 1-2 sentence summary for each article, not like a whole page.

I’m thinking there is an exclude tag like:
https://www.example.com/?cat=-123&feed=rss2
or something. Where would I put that in the post I want to exclude?
