en cherchant des infos sur la fonction get_template_directory_uri()
Retrieve template directory URI for the current theme. Checks for SSL.
Note: Does not return a trailing slash following the directory address.
In the event a child theme is being used, the parent theme directory URI will be returned, get_template_directory_uri() should be used for resources that are not intended to be included in/over-ridden by a child theme. Use get_stylesheet_directory_uri() to include resources that are intended to be included in/over-ridden by the Child Theme.
:codex:
Il faut donc la remplacer par la fonction get_stylesheet_directory_uri() et ça marche 😉
