RSS Feed Showing Comments Only?

This is actually happening on now multiple blogs. A perfect example of this is at https://junkylife.com/bi11i/index.php/feed

I should add that my feed validates and that I haven’t any plugins active:

https://feedvalidator.org/check.cgi?url=http%3A%2F%2Fjunkylife.com%2Fbi11i%2Findex.php%2Ffeed

I’ve got the same problem and had applied a fix (ticket 2379) to wp-includes/classes.php and the result was negative! This fix didn’t fix my problem. I still got RSS feeds with all the comments of my website.
When using the “Default Permalink Structure” my RSS Feed runs well. Using the “Permalink Customer Structure” with the values:
/index.php/%year%/%monthnum%/%day%/%postname%/
the RSS Feed fails and shows only the comments.
Thank’s for tipps

This worked for me, but not until I changed my permalink style to default and then back again….

I’ve changed the fixed row (fix 2379) in module: -> wp-includes/classes.php
but the fix DOESN’T work for me.

Then I found out, that:
When the URL has the following ending
-> /index.php/feed/
then only comments are displayed!
When I change the URL to the following ending
-> /index.php/?feed=rss2
the feed works and my posts are shown.
QUESTION:
Where can I change these values and set them to “/?feed=rss2” ?

I’ve change the call to RSS-Feed
from
-> /wpwetter/index.php/feed/
to
-> /wpwetter/?feed=rss

Now it works – Thank you
