Is not working anymore in my blog

I think that Chrome’s preview might have something to do with it. Were you using Chrome? I could get it working with older versions.

You are right. I tested in Firefox and it works but in Chrome and Edge doesn’t work ?? How can I fix that? Maybe I’m writing the code wrong or maybe it’s the plugin. I just want to print the image below the print button. Help please!

the reason it is not showing on the print page is because you are using lazy-load on the image:

<img class="alignnone size-full wp-image-40" src="/wp-content/uploads/2015/06/guiamandalas-1.png" alt="Mandala para colorear" width="600" height="600" data-jpibfi-indexer="0" data-lazy-loaded="true" style="display: block;">

https://www.guiamandalas.com.ar/wp-content/plugins/lazy-load/js/lazy-load.js?ver=0.6

Also of note: your site is loading an ancient version of jQuery, rather than the version that comes with WordPress:

<script type='text/javascript' src='//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js?ver=1.7.1'></script>

Version 1.8.3 came with WordPress 3.5 which was released back in December of 2012

How can I upgrade the version of jQuery?

Here is an article that should help:

Basically you will need to look in your functions.php and header.php file for where the official version jQuery that came with WordPress is being unregistered, something like:

wp_deregister_script('jquery');
wp_register_script('jquery', 'https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js', false, '1.8.3');
wp_enqueue_script('jquery');

Hi Baden or anyone. Can you help me? It seems that I have the latest jquery and I deleted Lazy load but I still have the same problem, I can’t print the images. Am I doing something wrong? Please help!

You need to use the full url to the image. Currently the images have src’s like so:

/wp-content/uploads/2015/06/guiamandalas-1.png

and they should be more like:

https://www.guiamandalas.com.ar/wp-content/uploads/2015/06/guiamandalas-1.png

Hope that helps!
