Rolling Back to Previously Used License Key
If you installed wrong license key for the control panel or a Plesk add-on, you can roll back to the previously used license key.
To roll back to previously used license key:
- Go to Server > License Management.
- If you want to restore a license key for your control panel, go to the step 4 of this procedure. If you want to restore an additional license key for an application, click Additional License Keys.
- Click Roll Back Key. You will be shown the list of properties for the key that you wish to roll back to.
- Click OK to roll back to the previously used license key.
Note. Using the rollback function again will revert Plesk to the key you originally used before the previous rollback.
