Hi,

I have local env and live server, both php 5.6.32 with Piklist 0.9.9.17

I have a setting and repeater field as follow:

/*
title: Clients
Setting: lc_settings
Tab: Clients
Tab Order: 3
*/

piklist('field', array(
 'type' => 'group',
 'field' => 'hp_clients',
 'label' => 'Clients',
 'help' => 'One logo per group',
 'add_more' => true,
 'fields' => array(
  array(
   'type' => 'file',
   'field' => 'logo_image',
   'label' => 'Client logo',
   'required' => true,
   'options' => array(
    'basic' => false,
    'modal_title' => 'Choose image',
    'button' => 'Select'
   ),
   'columns' => 8,
   'validate' => array(array(
    'type' => 'limit',
    'options' => array(
     'min' => 1,
     'max' => 1
    ))),
   'attributes' => array(
    'class' => 'regular-text'
   )),
 )
));

This is how I display the logos:

<?php if (!empty($clients)): ?>
      <?php foreach ($clients as $client): ?>
        <?php $attachment_id = $client['logo_image']; ?>
        <img src="<?php echo wp_get_attachment_url($attachment_id); ?>">
      <?php endforeach; ?>
    <?php endif; ?>

Here is the weird part

$client[‘logo_image’] is array on my local server ( the image ID is $client[‘logo_image’][0] and on server env $client[‘logo_image’] returns the ID itself.

If I leave $attachment_id = $client['logo_image']; it works on server, but not in local. Why is this inconsistency?
