I have a site with two languages. Once I have translated all custom field groups all work ok except the post object ones. None of them work. When I try to select a page a JS error appears http://www.XYZ.com/en/wp-admin/admin-ajax.php 404 (Not Found)
They work ok with the main language.
Thank you in advance for your help
I have the same problem, and not only for ACF admin functionality. So this is really a WPML issue. Setting the URL format to language parameter instead of directory resolves this.
Thank you, yes, setting the URL format to language parameter resolves it. But this is something new. Never happened to me before….
