How can I activate the popup zone

[Azhiya]

I have been trying to run a popunder, and I have found out I need a special zone type tag, however, this is not active in my system, I only have the four options, Standard, Text, Email, and Interstitial. How can I activate the popup zone type?

To enable the Pop up type of zone please follow the instructions given below:
Login as administrator. Go to Configuration Plug-ins
Click on the link “details” for Revive Invocation Tags.
Click on the “Settings” link in the bottom right corner.
There you will find ox Invocation Tags Configuration settings.
You can enable/ disable the invocation code whichever you want and save changes.
Once you enable the pop up type, you will be able to see the pop up type in zone properties page.
