Dear @monbauza
Thanks for your answer, but nothing changed.
I strictly followed your steps but I still get the same error.

Maybe cause I’m using the Italian version of WP (I was warned by the plugin that it’s only 98% guaranteed)? Maybe it’s due to PHP 7?
This is a more extended info about the configuration of my environment:
Versione WP: : 4.8.2
WPMU: No
MySQL Versione : 5.1.73
PHP Versione : 7.0.23
Salva Sessione Percorso : /var/lib/php/mod_php/session
CURL Libreria Presente : Yes
Debug File Permessi di scrittura : Not Writable
Yoast SEO: 5.6.1

I also turned the wordpress-seo folder of the plugin to 777 permissions, just in case… and nothing.

This is the complete verbose message in Console:
Uncaught Error: No locale meta information provided.
