Fatal Error in Version 3.2.3

I had no problems before the update. Now after the last update I get following on the_post_thumbnail function:

<b>Fatal error</b>: Uncaught Error: Class 'archon810\SmartDomDocument' not found in /xxxxxxx/wp-content/plugins/lazy-loading-responsive-images/src/Plugin.php:150

that’s my function:

the_post_thumbnail('category-thumb',
    array(
      'class' => 'project-list-img', 
      'alt' => $post_title)
 );

I have no idea what I’m or Plugin doing wrong.
