Hi there, I am really not sure if this is an issue for you but I would be really grateful if you would have a look and see if it is something that is influenced by X, particularly the latest upgrade as the problem has occurred recently.
I have woocommerce wishlists on my site. My problem is that when you click the add to wishlist button on a product, instead of doing what the product is set to do, which is stay on the product page it redirects to a blank page. The only way to get out of that is to use your back button on the browser which of course many users will be confused by. The product does in fact get added properly to a wishlist but I need to stop this blank page issue.
Could you take a look? Try this product - just select the variation options and the wishlist button at the bottom will be active: https://bespoke-weddingrings.com/shop/mens/18-carat-yellow-gold-mens-court-profile-wedding-band/
I’ll add my log in details in a private note.
