With WP Engine and a similar issue.
We have the following code
<?php $image = wp_get_attachment_image_src(get_field('home_hero_image'), 'home-slide'); ?>
<div class="home-top" style="background-image:url('<?php echo $image[0]; ?>');">
This image source always outputs HTTP. So when we access page with HTTPS it warns us this is unsecure content. I’ll see if I can add another way, but I thought using $image[0] was best practice.
