My website don't need user login function. Only system administrator could post new contents. How to remove user register and login in Drupal?
Thanks!
While it's technically possible to remove the login functionality, you shouldn't, because then your administrator could never log onto the site.
In order to remove the register functionality, you simply need to browse to admin/user/settings
(for Drupal 6) or admin/config/people/accounts
(for Drupal 7) and select the the "Only site administrators can create new user accounts" option.
