[Edited – I misunderstood the comment the first time]
The plugin does remove the actual feed URLs, and your issue is probably due to browser caching. Suggest you try clearing your browser cache or testing the URL in a different browser.
Hello,
I re-tested Disabled Feeds after your comment and same problem, all feeds are not removed.
The /feed is well removed, but the /comments/feed/ is not removed.
Can you provide an example URL?
Not at the moment, sorry :/
To test: before installing the plugin, go to feeds url (/feed & /comments/feed/). Install the plugin, refresh each feed page.
I have tested, and it works fine on a clean isntall of WordPress. That is why I asked for an example.
Will look into it further if you can provide a link.
