If you need to deactivate a licence can do so from within your WordPress admin area following the instructions below.
Navigate to your WordPress admin area.
Go to the plugin settings page. In this example: BookPress => Account Settings = Account
Select ‘Deactivate Licence’ at the top of the screen.
You will now notice a prompt asking you to upgrade the plugin. If you need another licence, you can get one there. If not, just ignore it or remove the plugin from this installation.
Note: You can reactivate the licence again by going back to Manage Licence and clicking Activate Licence.
Alternatively, you can access the Members Dashboard here.
You will receive your login credentials after your first purchase, and for security reasons, will have to update your auto-generated password upon your first login.
