Hi @ijelliti and welcome to our community!
First thing I usually suggest that people check is: “did we build the site in a different way than your local?” Usually we serve what we built, so you’ll probably want to be debugging your build instead, as described in this doc: [Support Guide] Debugging Netlify site builds
The easiest way to tell if this is the case is to download a copy of your latest deploy from the icon shown in my screenshot on its deploy logs page:
and see if the files are different than a copy of your local build for the same commit.
