Favicon doesn't work

[AntonioBisconti]

Hi, i want to set a favicon for my website. I've used Hugo with PaperMod theme. I followed documentation to set it FAQs Adding Custom Favicon(s) and I used favicon.io to generate the files. This is the directory structure:

As indicated on favicon.io, I also inserted these lines of code:

  <link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">
   <link rel="icon" type="image/png" sizes="32x32" href="/favicon-32x32.png">
   <link rel="icon" type="image/png" sizes="16x16" href="/favicon-16x16.png">
   <link rel="manifest" href="/site.webmanifest">

under ~/Documenti/BLOG/layouts/partials/extend_head.html. and ~/Documenti/BLOG/themes/PaperMod/layouts/partials/extend_head.html . Despite this it doesn't work. I also followed this github discussion How do I set the favicon for my webpage about PaperMod Favicon, but nothing.
Thanks for your help!
