The plugin is changed. This is my working solution:
Locate the file using FTP or a directory browser: */wp-content/plugins/wpseo-woocommerce/wpseo-woocommerce.php
Around line 82 find:
$this->license_manager = $this->load_license_manager();
And change it to this:
// $this->license_manager = $this->load_license_manager();
Done!
