Error 404 - URGENTw

I’ve just uploaded the latest version (8.2.2) and now I can’t preview any of my future posts. All I get is a 404 error page. The redirection is not functioning. I’m using WP, should I get a plungin ? But most of all, why ? It’s going to be the same issue if I publish my posts.

Should I go back to the previous version ?
Thanks !

I just installed the Penci Review and I get this message : Désolé, vous n’avez pas l’autorisation de prévisualiser les brouillons. Sorry, you don’t have the authorization to preview the posts

What is going on ?
