I am using doxygen for sometime. I previously generated a documentation for my source code with namespaces. It was working OK. But now I created a new project for my new sources and Doxygen does not put Namespaces tab to the documents although SHOW_NAMESPACES is YES and there are lots of namespaces in the source code. The namespace of classes are seen when selected but I dont have the tab.
What could be the problem?
