I got a somewhat similar error after updating from 0.5 to 1.0
An error of type E_ERROR was caused in line 17 of the file /home/lmtproducts/public_html/wp-content/plugins/sku-shortlink-for-woocommerce/vendor/wponion/wponion/builder/helper/container/class-helper.php. Error message: Interface ‘WPO\Helper\Interfaces\Container’ not found
Might be a composer issue, not sure.
