  • This suggests that the $fields parameter is not an array as expected.

    Can you please test this out by editing the file ‘pro/fields/class-acf-field-clone.php’ on line 119 and change the start of the acf_get_fields function to:

    function acf_get_fields( $fields, $parent ) {

    // bail early if empty
    if( empty($fields) ) return $fields;

    I have fixed this issue earlier when I was using shared hosting but after moving to WordPress managed hosting, I have never got any error like this because their platform is easy to use and compatible with WordPress versions.
