Fatal error: Call to a member function get_upsells() on a non-object in /plugins/woocommerce/templates/single-product/up-sells.php on line 16

When using the plugin Woo Detail Product Page Builder, I get the above error.
It causes the details on the admin of the single product page editor to go blank and just show a white page.

Not sure how to fix it. Any help would be appreciated.

Disabled all other plugins to see if they were causing issues, only Woo Detail Product Page Builder caused issues. All themes and plugins are up to date, most current wordpress and woo commerce is installed.
