First problem: After you fill all the required fields and press Save button nothing happens, in demo and my development site too.

Second problem: "Add to Wishlist" button didn't work inside product. Working a little from category page, but no message like "You have adding product in your wishlist."

Third problem: in Wishlist page, if you delete one of item, after press button "Delete" their haven't show ( Sure? | x )
Also you need to reload page, deleted item didn't disappear without it.
