Good but some problems
A good extension but some conflicts with other plug in (woocommerce) so I partially disabled

Des heures de recherche
Après des années a avoir utilisé ce programme, je me retrouve avec des headers qui ne s'affiche pas sur certaines pages (site de 350 pages) , plus de 10 heures de recherche avec l'IA, pour enfin découvrir que c'est jetpack qui pose problème ( je travail avec WP 6.9 et maintenant 7.0 et Elementor pro et Hello ), très bon programme, mais si vous avez des problème sur votre site, désactivé Jetpack et vidé votre cache avant de chercher plus loin
