Reply To: validate_value filter doesn't work

I am experiencing exactly the same problem reported here. My validate value filters never get called. They are in my theme functions.php file and I have used the code provided above.

I am seeing acf/save_post work correctly btw. But acf/validate_value never does anything. Any help please? How do I debug this.

I am running a brand new WP site (as of a week ago) on PHP 5.4

To isolate this issue I dropped my child theme and I am using plain twentyseventeen. The only change is the top of functions.php as shown here

<?php

add_filter('acf/validate_value', 'my_acf_validate_value', 10, 4);

function my_acf_validate_value( $valid, $value, $field, $input ){

	return "is that working?";
}
