EDIT: [SOLVED] Page was cached on server, I went to c-panel and purged cach for domain and now it works fine.
I've been banging my head with this one for hours, so any help is welcome.
I have a new wordpress install. I've added a theme Illdy and I've imported dummy content via Illdy Companion. After some time working on the theme, I've noticed that while logged out homepage doesn't show any changes but displays dummy content.
So I deleted all plugins and theme and went back to twenty seventeen, but it still displayed dummy content on homepage, in plain html since the theme was removed. Then I reinstalled whole wordpress, found a new theme and it now displays twenty seventeen on homepage while logged out.
In short all changes to the website are visible while logged in, and when I logout it shows homepage from different source.
There are no plugins for caching.
