I have same issue, too
My Website: https://tctest.cafe24.com/wishlist/view
When I add wishlist, it’s fine. but when I tried to remove wishlist or click ‘add cart’ button, I got error message like ‘404 error’.
This is summary..
– Woocommerce Version: 2.3.5
– YITH wishlist version: 2.0.4
1. remove wishlist -> there is no response
2. click ‘add cart’ -> 404 page error (add-to-cart.php)
How could I fix this problem?
Thank you!
