The person who creates a HappyFox account is the account administrator of that account.
Only an account administrator can select a different person to be the new account admin.
Follow the below steps to select the new account admin:
Step 1: Log in to HappyFox with the current account administrator's credentials.
Step 2: Head on over to Manage >> Account Settings >> Basic Settings
Step 3: Click the field under Account Administrator, and select the respective agent member as the new account administrator.
Step 4: Once you've made all the necessary changes, click Save Settings to confirm.
After this, the new Account Administrator will be provided with all the necessary access privileges they are entitled to. If it seems like there hasn't been any change, logging out and logging back in should fix it.
