On discussion list by tag it seems that easydiscuss is generating RSS feeds. The problem is that those RSS feeds are broken and generates several error in the Google Search Console.
You can check that here: https://www.joomunited.com/component/easydiscuss/tags/k2-articles
Hit F12 and search for RSS, you will find broken link in the chrome dev tool (or any other).
My question is how could I make it work or simply disable it? Maybe it's also on other views but I'm not sure.
