hello,
thank you both. I solved the problem placing a copy of genericons folder into my Hoffman-Child theme folder.

Hello Calvin,
Thanks for your response! I did exactly as you wrote. I have icons (but not social icons: https://prntscr.com/5pbiyh). This icons are active, they correctly linked to my social media).

It works, thanks u Eva!
Sorry, I do not know the answer to your question

I did as Eva wrote. Now I have “slider” (featured) and I have “gallery” in the post.
BUT I want to have only slider as featured.

yes, featured image is 1200px width
but post media are resized
