Problem/Motivation
From a number of the ticket pages, navigating back to the site produces a unexpected error. I am unsure if this is a symptom of something else, or the core issue!
Steps to reproduce
1) visit /admin/structure/commerce_ticket_types
2) Select 'back to site' from the drupal admin bar.
3) The website encountered an unexpected error. Try again later.
