The user level of the login web user is low.

Web users of level 2 or lower are monitoring users and can use only the ping and tracert functions. Web users of level 3 or higher are administrator users and have all operation rights of a web page.

You can run the local-user user-name privilege level level command in AAA view to set the user level of the login user to level 3 or higher. The login user then has all operation rights of a web page.
