I noticed yesterday that my "secondary" pages have disappeared.
To be specific, I have a page called /reading-list, and then several pages called /reading-list/2007, 2008, etc. However, starting yesterday afternoon, clicking on links or typing in the URL for the secondary pages just loads /reading-list.
I was able to get at the code for /reading-list/2008 by going through Manage>Pages>Edit, but the View link still took me back to /reading-list.
Any ideas?
