By default, the plugin allows its functionalities both to registered users and to unauthenticated users. However, you can choose to linit wishlist use only to registered users by enabling “Disable the wishlist for unauthenticated users” option of “Settings” section of the plugin settings dashboard.
As soon as they try to add a product to the wishlist or display Wishlist page, they will be redirected to “My Account” page and a message will be shown that invites them to register.
When plugin functionalities are enabled also for unregistered users, it is shown a message by default, right inside “Wishlist” page, that invites them to log in. This message can be changed in “Show login notice before wishlist table” field.
Use %login_anchor% placeholder to show login link; leave empty to hide.
