Hello, @Giuseppe,
The issue you are facing is because you are using the Multiple headers feature on your site, You have used the condition for the default header to show it on your site home page: https://postimg.cc/Z05gGh8m https://postimg.cc/jWCnV2SN
I have removed the condition from the Multiple headers >> default header and now your site home page is working fine: https://postimg.cc/4HnJ8LbT
