Enabling administrator privileges
You can provide any user with the ability to log in to the site control panel as well as the user control panel.
To add a user with both site and user control panel access, make sure the site administrator privileges check box is selected on the user information form in the add user wizard.
To give a current user site control panel privileges:
On the top navigation bar, click users.
On the users list, select the user you want to give privileges to, then click overview.
On the user account Information form, select the check box next to site administrator privileges.
Click Save.
The user is granted site administrator privileges and can log in to the site control panel.
