Modifier morceau de code php

Bonjour,
Je cherche comment supprimer l'affichage de la right sidebar. Uniquement sur les pages boutique Weecommerce de monsite Wordpress (thème Attitude).
La solution pourrait se trouver dans le fichier sidebar-extensions.php . Sans doute modifier un bout de code.
Je n'ai pas, hélas, la compétence nécessaire pour interpréter les lignes de code php.
Merci beaucoup de me lire.
Pierre
