I must have goofed something up. Recently our site just started not showing the bread crumb trail when browsing the category tree until you land on a product. Once you select the product the entire crumb tree suddenly appears. If you jump to any topic, like a FAQ page, the "Now In: ..." appears correctly. But as soon as you select a branch of the category tree, the trail for "Now In:" goes to blank and you get nothing until you select a product, then it all comes back correctly.
What have I goofed up?
