Bonjour merci de votre réponse, désolée mais je parle très mal anglais.
sauf erreur de ma part, l’ennui vient des asides et la balise read more ou la balise fermante </p> est manquante.
les balises de fermeture aside sont fermées à l’envers,(fichier right-sidebar.php) enfin toujours si je ne me trompe pas!
