Running Drupal 7.59
I have added a field to a field collection using the Structure->field collections->(collection) menu
I edited a page where the field collection is used, and added content to the field.
The new field is retained when I revisit the edit page, but it does not show up in the field preview, nor when I display the current page.
When I add a field to the structure, do I need to do something else to enable display?
I have no idea how to go about debugging this!
