I have a single site collection that was previously a MOSS 2007 site. This site collection has about 15 webs, and some of those have a number of subwebs underneath them. The top navigation bar is set to display all subsites, and well as the sub sites underneath them. This works without issue, and I see all root sub sites displaying, as well as their children.
After the upgrade, I have a single subsite that is not displaying in the top navigation bar. It shows in the tree control for the navigation that it is in there by default, but it does not render on the page.
What could cause I subsite navigation node not to show? I don't think it is permissions...This subsite is open to everyone. I do not see it as the Farm Account, and it is NOT hidden.
