I am trying to: translate a website in Chinese.

Link to a page where the issue can be seen: hidden link

I expected to see: the duplicated media thumbnail for each Lecturer

Instead, I got: some thumbnails and some broken Urls.

Please note that:
1) I added a new language (zh-hant)
2) I duplicated the media from WPML -> Settings
3) I duplicated the ACF fields
4) I fixed the unassigned settings for ACF fields, assigning "Copy" to image fields
5) I duplicated the lecturers' entries.

Images are, as expected, linked to the translated entry but then they are not randomly showed on the page.

Also note that if I open the record for a lecturer and then I update it, the image shows up.
Unfortunately I should do that for 200 entries.
Why did it happen?
Is there a way to fix this?
Thank you in advance for your help/support.

Hi Raja,
Thank you for reaching me.
I updated all the WPML plugins to the last version.
Issue is still in place.

Please note that I clearly wrote that by updating the Lecturer's custom post, the issue solves. I'm just looking for a bulk solution as there are hundreds of entries.

Currently, in production I'm getting:

<img src="<br />
<b>Warning</b>:  Illegal string offset 'sizes' in <b>/home/rafflesmilano/rm-modaedesign/wp-content/themes/rm-modaedesign/_partials/section__fc-people-grid.php</b> on line <b>21</b><br />
<br />
<b>Warning</b>:  Illegal string offset 'squared-800' in <b>/home/rafflesmilano/rm-modaedesign/wp-content/themes/rm-modaedesign/_partials/section__fc-people-grid.php</b> on line <b>21</b><br />
1" alt="<br />
<b>Warning</b>:  Illegal string offset 'alt' in <b>/home/rafflesmilano/rm-modaedesign/wp-content/themes/rm-modaedesign/_partials/section__fc-people-grid.php</b> on line <b>21</b><br />
1" style="width: 100%;">

while in my local environment I'm just getting:

<img src="1" alt="1" style="width: 100%;">

PHP code is:

<?php $img = get_field( 'img' ); ?>
						<?php if ( $img ) { ?>
							<div class="img"><img src="<?php echo $img['sizes']['squared-400']; ?>" alt="<?php echo $img['alt']; ?>" style="width: 100%;"/>
								<div class="hover">
									<div class="quote"><?php the_field( 'quote' ); ?></div>
						<?php } ?>

ACF image field is set to return an Array.

Functions.php contains "add_image_size()" instructions for all needed sizes.

Update: As far as I can see, for some reasons, some images are returned as ID rather than as Array.
Attached you can see a screenshot with an "echo $img;" on top of each image.

I found this thread: and I applied some of the advices.

1) I set the _img system field for that custom post and updated the page.
2) I batch duplicated all the posts for that custom type.
