Sidebar and footer (facebook/instagram/..) disappeared from the main page

Hello,

I have been using Virtue since a year now and everything went perfectly well. Two weeks ago I noticed that the Sidebar and the footer wer not appearing ont the main page.

So if you go on : https://victorienlanon.com/ you wont see it on the right and on the footer.

When you go on : https://victorienlanon.com/category/recettes/ everything is showing up on the right side of the website.

I can’t find the trick to make it appear again and my WP skills are a bit rusty at the moment so I’ve spent time looking for an answer but did not find any.

Do any of you get an idea of what could cause this ? If you need further informations I will be happy to tell you.

Have a nice day,

Julien
