Your theme (ticketbox) contains outdated copies of some WooCommerce template files. These files may need to be updated to ensure their compatibility with the current version of WooCommerce. Troubleshooting suggestions:

Update your theme to the latest version. If no update is available, contact the author of your theme with questions regarding compatibility with the current version of WooCommerce.
If you have copied a template file to change something, you will need to copy the new version of the template and apply your changes again.
