Granting admin privilege to a user allows the user to perform more tasks within the system. Before you can grant a privilege to a user or member, you should be an admin user that has been granted that privilege by the admin or superuser being the system owner.
On the left menu, click on Members Mgt. and select Manage Members
Search for the username or click on the Edit by the right-hand side of the user type to grant or revoke privilege(s).
On the Permissions dialogue box that appears, select the Role e.g. User or Admin
Make necessary changes such as selecting options or deselecting to grant or revoke privilege(s) and click Update Now when you are done.
Note: To change the user type for a new user who has not logged in to the system before, for example, from User to Admin or from Admin to User, the user has to log in first. The user has to activate his or her account by going to the email inbox, or the Admin can activate it manually
In the left menu, click User management and select User permissions
On the User Default Permissions page, select a role, e.g. Admin or User from the Choose a Role drop-down menu, make necessary changes based on the role you have selected.
