When I click "Add All to Cart" on the wishlist page, I get a 404 error and the address in the bar is http://www.blahblahblah.com/wishlist/index/allcart/. The items are not added to cart.
A slightly different error occurs if I "Add all to Cart" from the share wishlist email, it then just goes straight to homepage.
I am using Magento CE v22.214.171.124 with unchanged version of /template/wishlist/view.phtml and have not changed any core files.
It looks like it's getting the wrong url?
