Hi! Just wanted to update you on this. I had a programmer look at it and apparently the issue was that the $posts global variable was being overridden.
When I searched through the code, the only places I saw that variable mentioned was in the main WordPress files, the ACF plugin, and the Event Calendar plugin (which I tried disabling and didn’t make a difference). So I’m not sure exactly what was the culprit there, but once that variable name was changed, it worked fine.
Here’s the code that ended up working in case anyone else has a similar issue:
<?php $store_type_posts = (array) get_field('store-type'); ?>
<?php foreach ($store_type_posts as $store_type_post): ?>
<?php $store_type_logo_id = get_field('store-type-logo', $store_type_post->ID) ?>
<?php if ($store_type_logo_id) : ?>
<?php $image = wp_get_attachment_image_src($store_type_logo_id, 'Store_Logo'); ?>
<?php $alt_text = get_the_title($store_type_logo_id); ?>
<img src="<?php echo $image[0]; ?>" alt="<?php echo $alt_text; ?>" width="<?php echo $image[1]; ?>" height="<?php echo $image[2]; ?>" class="plain" />
<?php endif ?>
<?php endforeach ?>
