Navigate to the Settings → Portal Settings to set up your portal details. Also, from the ‘gear’ icon, you can navigate to the General Settings. [1]
You can set the General Settings as follows:
Name: Insert your Portal Name.
Logo: Upload the Portal Logo.
Admins also have an option to display the site under the maintenance page if your site is under maintenance. Enable the Site Under Maintenance switch and select the page you want to display when your site is not working so that your users are not able to access the portal. [2]
