Static front page

I have made 2 other websites with that, but i didnt have that prolem before.

Either the theme’s homepage setup has changed, or possibly you’ve forgotten how you configured the homepage for those other themes.

According to the documentation, the theme doesn’t use the content in the “homepage” page. The homepage content is configured in the theme’s configuration panel.

Hi @karlip,
After selecting a specific page as static make sure that all your content are added to that page.
Once content are added you can save it and visit your website.
Your content will be visible at homepage.
