$site_features = get_field('site_features');
if( $site_features ): ?>
<ul>
<?php
// notice the missing "s"
foreach( $site_features as $site_feature ): ?>
<li><?php echo $site_feature; ?></li>
<?php endforeach; ?>
</ul>
<?php endif; ?>
What does this do?
foreach( $site_features as $site_features ):
The first iteration of this loop sets $site_features (an array) to the string of whatever is in the first array value. This is the same as doing
$site_features = $site_features[0]
and this breaks your loop. Lets say that the first value of that array is “Some String”, then the next itteration will set $site_features equal to the second character of the string.
