Drupal administration

Here are some notes about common administrative tasks that often confuse new Drupal administrators.

New module = new permissions

Remember this: generally speaking, whenever you enable a new module, you must visit:
Administer > User management > Access control
to check for additional permissions for this module.

If you are not user/1 but have full administrator role, you must check all new permissions for the administrator role to gain access to ALL new setting pages and to all new functionality. Additionally, if necessary, you can selectively give new permissions to other roles.

Once you have checked the permission, another page that is often useful to visit after enabling a new module is the list of administration pages by module at /admin/by-module :
Administer > By module (tab).
