Menus have suddenly gone crazy -- they won't appear where I want them. It seemed pretty easy: Create a main menu on the front page which then branches off to sub-menus on inside pages. I create one menu on the front page and it works fine. Now I try to create a menu that appears only on an inside page (using node/xx as the reference in "appear only on these pages" option) and they don't appear. Now it gets even odder. I create a book with child pages. It never appears on inside pages and only once appeared on the front page -- now the book menu won't appear at all. This is seriously driving me nuts and I wonder why I should keep hitting my head against the wall...but then I remember, besides all of these infuriating glitches, Drupal is a pretty good CMS.
Anyway, what am I doing wrong with menus?
