ONE TIME SETUP
Your online licence manager
Create your provider account. This manager is separate from school accounts.
In Hostinger File Manager, open /home/u560194369/domains/georgiahillmontessorischool.com/gehmos-license-private-49afcff6fef8/setup_token.php and copy the code between the quotes. This confirms that you own this server.
Restore a manager backup instead
Restore only into this new, unconfigured manager. Your original signing key and schools will be recovered.
