I'm experimenting with Umbraco 12 and have had this problem come up a couple of times now. Last time I just reinstalled from scratch as I was only experimenting to get familiar with Umbraco 12.
I have a Document Type named "HomePage". As soon as I make any change to this Document Type U12 stops working and refuses to display and page with this Document Type, other pages with different Document Types work just fine.
Any idea how to resolve this? I've restarted IIS and no change. Other than creating a couple of Document Types and very simple templates and adding a couple of content pages, it's a completely empty fresh installation of U12.
