Hello Chiara,
Do you happen to have a link to your site you would be willing to share? That will help us see what you’re referring to and be able to make a recommendation from there.
It is worth noting that there is a .events-archive class on the body tag of any archive page and that can be used to hide the element on those pages.
Also, I see this thread is posted in our Translations forums, but I’m going to move it over to our Events Calendar PRO forum. Just wanted to give you a heads up because you will need to sign into your account to reply. 🙂
Cheers!
Geoff
