Author link now go to home page

Author pages are per-site, so you should have

https://www.quercialuce.it/author/YOURNAME

and

https://www.quercialuce.it/de-vino-blog-sul-vino/author/YOURNAME

Thanks for your replay.

Sites are
1)https://www.quercialuce.it/
2)https://www.quercialuce.it/ricette/

Since I installed the multisite blogs, I have these links
1)https://www.quercialuce.it/blog/author/NAME
2)https://www.quercialuce.it/ricette/author/NAME

where blog1 (the first one, the old one) wordpress put in my post slug /blog/

so the new site “blog2”
https://www.quercialuce.it/ricette/
have to be correct but doesn’t work as the blog1

Thank you

Probably something w/ Yoast seo plug in cause this.

In Indexation/indexation rules and archive settings…but not yet solved at all

No, that’s right.

It’s because you’re using a subFOLDER. https://www.quercialuce.it/blog/author/NAME is correct for the main site.

https://www.quercialuce.it/ricette/author/NAME is correct for the site ricette.
