Voici comment contourner le problème des boucles de redirections que l’on peut parfois rencontrer avec prestashop 1.6
J’ai expliqué dans cet article comment afficher un site installé en local via un ipad ou iphone (ou tout autre mobile). Le problème c’est que souvent cela génère une boucle de redirection. Voici deux overrides qui vont vous permettre de contourner le problème.

Si vous avez un problème de page introuvable essayez de désactiver la réécriture d’url et la redirection vers l’url canonique.
Enfin voici le même correctif pour prestashop 1.5
