ADF stopped working after the update.

Hello,

my working version of ADF is 4.4.12
This is the syntax I’m using:
$fields = get_fields();
$field1 = $fields[‘logo’][‘field1’];
$field2 = $fields[‘field2’];
$field3 = $fields[‘field3’];

I have decide to update to the last version. But ADF fields were not showing.

How to call them proppery in PHP?
Do I need to update (safety reasons, resource usage…)?

Thanks!
