Favicon

Hi everybody,

After trying to get my favicon to work those ways :

  • In WP (back) root folder
  • In WP (back) Theme folder
  • Setting my favicon in “customize” part of WP

I stil can’t make it appear, although it appears on my back wp website.
Those are the links related to my problem :

https://www.silico.fr/ (front)
https://www-back.silico.fr/ (back)

I read all other topics on the forum about favicon but i don’t understand where I should put it eventually.
Any idea ?

Thanks a lot !
Vincent.
