I upgraded from Drupal 5 to 6 and the menus are no longer displaying within the site. I've rebuilt the menus using the directions listed at http://civicactions.com/blog/how_to_rebuild_the_menu_in_drupal_6 (visit the admin/build/module page) as well as truncating the cache_menu table.

The primary_links menu is not displaying and I noticed some other odd issues such as the views link on /admin not displaying even after installing the views module and having proper permissions.

Suggestions welcome.
