I've been going around in circles with trying to get breadcrumbs working as the client wants them on a Drupal 7 site with a custom Zen theme working. I've built the site out and it requires the titles being added to the breadcrumb trail.
The issue is, the crumbs only display correctly with the theme developer module enabled. I know you can set the Zen theme's settings to append content titles to the breadcrumb trail, but this doesn't seem to work (either through specifying through the UI, or by changing the settings in the
MYTHEME.info file). They do however correctly display with the
theme developer module enabled. For a host of reasons I can't have a live site with this module enabled.
1) How do I get the breadcrumbs working properly and why doesn't it work through the UI or in code?
2) How can I resolve this apparent conflict?
