No navigation warning after deleting fields?

  • Hi,

    Why is there no navigation warning after deleting a field?

    I get a warning when I ADD a field and trying to navigate from the field group, but not after deleting one or multiple fields.

    ACF Version 5.3.10

  • Hi @niclasu

    You can fix it by using this code in your functions.php file:

    function my_acf_field_group_admin_head() {
        <script type="text/javascript">
            acf.add_action('remove', function( $el ){
                window.onbeforeunload = function() {
                    return true;
    add_action('acf/field_group/admin_head', 'my_acf_field_group_admin_head');

    I hope this helps 🙂
