• Has anyone implemented this with the Advanced Custom Fields plugin?

    The following seems to work for core custom fields, but not with the plugin.

    // Also obfuscate emails appearing in custom field values
    add_filter( 'c2c_obfuscate_email_filters', 'change_c2c_obfuscate_email_filters' );
    function change_c2c_obfuscate_email_filters( $filters ) {
        $filters[] = 'the_meta';
        return $filters;
    }
