Hi francois.jourjon,

I just visited to your site and your parent theme css is not called. So once you add this code that we have provided.

/*
Theme Name: Clean Retina Child
Theme URI: https://www.themehorse.com/themes/clean-retina
Author: Theme Horse
Author URI: https://www.themehorse.com
Version: 2.0.1
Text Domain: cleanretina
Template: clean-retina
*/

@import url("../clean-retina/style.css"); 
.entry-meta .date {
display: none;
}

Thank you!
