I have had a look into this and it seems I am using an if statement that has since been changed since PHP V5.3.
I other words in PHP V5.3 this code shows all the ACF field data
if(get_field('name'))
$field_name = "name";
if(empty($field_name['name'])){
echo " ";}
else
....
However if you upgrade from 5.3 upward this statement stops the PHP fields showing … take the ‘if’ statement out it all shows again.
So it seems I need to upgrade this ‘if’ statement somehow
