Sorry, but we don’t know what kind of cache is still enabled on your website. To verify that it is a cache problem we performed the following test:

1. We change the position of the header logo and saved it https://gyazo.com/fb57246c112e5391eaa9952861d88788

2. But for not logged users it is still in the same position https://gyazo.com/16219f8b8e1e5d08120e84a00f6690a9

It means that the wishlist page comes from cache for all not logged-in customers.
