rss feed

Disable all plugins and check.

it didn’t worked from the beginning

It looks like your RSS is working, but that it has nothing to show. At a guess I would say that your site is geared to show pages. I think that the RSS feed only shows posts.

A quick search on Plugins for RSS Pages should help. For extra help the first return looks promising! https://www.ads-software.com/extend/plugins/rss-pages/
