Repeated error in debug.log

Hi I’m getting a repeated error in the debug.log at seems to be from upset lite.

The error is:

[17-Jul-2018 12:38:58 UTC] PHP Fatal error: Uncaught Error: Call to a member function get_image() on boolean in /home/xxxxxxxx/public_html/wp-content/plugins/woo-unlimited-upsell-lite/includes/class-woocommerce-unlimited-upsell.php:519

Looks to call get_image() incorrectly somehow.

Also I get a get_title() error from viewing the admin area.

Any help in fixing the error would be a help.
