- Log into your account on the main site: https://onedollarplugin.com/account/login/
- From the top-menu, under My Account, select Purchases
- Then select View Licenses
- Then select View Upgrades
- Select the site license pack you want and proceed through the checkout just as you did before.
Note: If you, for example, want to upgrade to the 3 site license subscription, the upgrade price is calculated pro-rata, taking into account the price also paid for the original subscription. Rather than create a new subscription, the system will update the original subscription and replace it, in this case, with a new 3 site license subscription.
