How to Network Activate AdRotate Pro
You'll need an AdRotate Pro Developer License to proceed with this guide. You can buy a license here.
Standalone vs. Network
If you have a Wordpress network (or multisite) set up then you'll no doubt know about network activating a plugin. The practice of enabling a plugin for all your blogs essentially forcing the blog user to use that plugin (or at least have it active).
License
In order to Network Activate and use AdRotate Pro you need a Developer license.
Normally the license activation is located in the AdRotate Settings dashboard. Only a Developer License can be used for Network Activation.
Because you may be deploying AdRotate Pro to multiple users you do not know or necessarily trust the license information is hidden from the AdRotate settings when AdRotate Pro is network activated.
Instead you go into My Sites > Network Admin > Settings You'll find a new AdRotate Pro menu. In it you can manage your license and some basic network settings.
