Error when resizing image

[doolak]

Hello there,

hope all of you are fine and healthy. I wish you all a happy second Advent Sunday!

I have a little problem using the resize function on one page - oddly enough it works fine on another page.

The code I use is the following:

<?php $image_resized = $page->product_image->size(806, 1028) ?>
<a href="<?php echo $image_resized->url; ?>" class="lightbox-gallery-3 mfp-image">
  <img src="<?php echo $image_resized->url; ?>" alt="<?php echo $title; ?>" /></a>
       

When trying to open the page I find the following error in the logs:

On the homepage I use a very similar code and it works fine:

<?php $image_resized = $four_boxes_box->four_boxes_bild->size(1090, 494) ?>
<img src="<?php echo $image_resized->url; ?>" alt="" class="wow scaleOutIn" data-wow-duration="1.2s" />

Does anybody has an idea what could be the problem? I am using the not working code in a PadLoper template, but as I can't imagine that this makes any difference I wonder why it doesn't work on one place but works on the other.

Kind regards, Christian

OMG - I found the problem... 

I have changed the field name of the image and didn't change it in the template... ?

Everything works fine now again!

I wish you all a happy and peaceful Advent season!

Cheers, Christian
