Please note the system is designed to display information and Menu items that you have access to as per your assigned role(s).
For example. The below will only occur when the user is either not assigned a Role or if the role assigned is not given permissions.
This can be verified on Administration > Users > Roles sections > Verify that the user account is assigned a Role.
If the user account is assigned a role, you will need to verify if the Role has permissions assigned in Administration > Roles > Select the Role assigned to the User.
Should you want to restrict access see this article. How to restrict access to certain part(s) of the system
