I'm using CiviCRM 4.7.16 with Drupal 7.
In the previous versions, the invoice tpl file can be found by viewing the page source html in the browser. It's in a comment line and it is something like
<!-- xxx.tpl file invoked ... -->
But I couldn't find these comment lines when viewing source in CiviCRM 4.7.16.
How do I find the invoked template in 4.7?
