Q: I am using Advertisement Factory I need to set up the Paypal feature Could you help me on how to do that?

A: You'll need to go to backend / Advertisement Factory / Payments / Payment Gateways / Paypal and set Enabled to Yes and make sure you fill the Email field with your paypal email address. Also make sure that Use Sandbox is set to No if you are not testing and going live. Create some prices for the advertisements you want to sell from backend / Advertisement Factory / Prices. That's all. When user will try to purchase ads on your site, the payment method Paypal will be available and they can pay using Paypal.
