Looking through my Google Webmaster Tools, I noticed some errors that involve the Wishlist feature. The page doesn’t even load or send you to a 404 page.
The target URL doesn’t exist, but your server is not returning a 404 (file not found) error. Learn more
Your server returns a code other than 404 or 410 for a non-existent page (or redirecting users to another page, such as the homepage, instead of returning a 404). This creates a poor experience for searchers and search engines.
