I am having the same problem with categories (still.) First the hierarchy worked. The next day it became flat and the sub-categories were not listed. Then I renamed categories in hierarchy order. It worked. Then it worked again and I renamed some of the sub-categories. But have been unable to rename all of them. I get the error Category not updated! I have sent 3 emails to support with no response at all. Can you help? I have noticed references to bugs fixed and not fixed and will be fixed ASAP (2 days ago.)
