PHP version compatibility

Hello and thank you for the amazing work 🙂

I’m running into a little problem:
Our website using ACF works like a charm in local servers but it’s crashing the website on our pre-production server. The php version is 5.3.3. We tried also on another one who is even older (5.2.10) and we got exactly the same result.

The code is the following:

<?php

$args = array( 'post_type' => 'header_banners', 'posts_per_page' => 1);
$loop = new WP_Query( $args );

?>

<?php while ( $loop->have_posts() ) : $loop->the_post();?>

<?php echo get_field("image")['url']; ?>);
<?php the_title();?>
<?php echo  get_the_content();?>
<?php echo get_field("url");?>

<?php endwhile;?>

The get_field functions are stopping php execution (I got no error message even with WP_DEBUG to true).

We are trying on a third server just in case (I’m not sure about the php version though), but maybe you got an answer that can be very helpful for us 🙂

Thank you very much for your time !
