Had the same problem. This solved it for me: Go to themes/prestashop/product-list.tpl and remove {if ($product.allow_oosp || $product.quantity > 0) && $product.customizable != 2} getPageLink('cart.php')}?add&id_product={$product.id_product|intval}{if isset($static_token)}&token={$static_token}{/if}" title="{l s='Add to cart'}">{l s='Add to cart'} {else} {l s='Add to cart'} {/if} Good luck!
