Child pages not showing up in nav or breadcrumbs.
PermalinkI don't have any attributes set for the child pages aside from Meta data and exclude from nav.
I'm using autonav
If you're using an unmodified auto-nav block then the only thing I can think of is one of your block options are not set properly.
Care to post a screenshot of the block options for the auto-nav block?
1) Are any of the exclude page properties set on the child pages?
2) Are you using the auto-nav or page list block or are you displaying the pages programatically?
