Permalink in preview snippet editor missing

Hi!

My “home” website is showing 404 error.

Well, I havent change anything in my permalink structure and I tried the recommendation to just click the save button in permalink menu point, but it doesnt help.

I just did some SEO optimization with rank math and now my page cannot be found anymore – but only the home page, all subpages still work.

Any idea how to solve that?

Thanks a lot!
