I had the same issue...I modified the php.ini upload_tmp_dir = /var/www/vhosts/{host_folder}/upload_tmp...also I needed to add code to crop.php to include the $_SERVER['DOCUMENT_ROOT'] in crop.php...

`<?php class CropAvatar { private $src; private $data; private $dst; private $type; private $extension; private $msg; private $uri;
