I am using ACF Pro 5.4.5 in one of the blog application that I have. When I update the user information, it is making a call to the admin-ajax.php and it is returning 200 success, but after that the page is redirected to a page https://mydomain.com/404.userinfo.json?_userID. This causes to show the 404 page and not the user editing screen.
For the Ajax call, it is passing the action as acf/validate_save_post and so I think this is related to the ACF plugin. Can you please help me to fix it ?
Last week, we released ACF 5.10 🎉 This update includes the brand new HTML escaping feature, which helps to keep your ACF-generated content safe. Learn about this and other new goodies in the release post: https://t.co/p9gKUYmdDQ
