I’m using a page builder plugin (e.g. Visual Composer) and my protected products are showing
Some page builder plugins such as Visual Composer include shortcodes for displaying WooCommerce products or categories on a page. These may not work with the privacy options in WooCommerce Password Protected Categories. For example, if you are displaying your most recent products on the homepage then products from protected categories may appear, even if you have unticked the ‘Catalogue Visibility’ boxes in the plugin settings.
You can fix this problem by manually excluding the protected products or categories from the page builder element. The exact process will depend on the page builder, but there is often an option to exclude specific products or categories from these elements.
