My sale tracking code is OK, but sales are not tracked
You have probably forgotten to insert the click tracking code into the landing page (destination URL of your banner). Sales cannot be tracked without click tracking. When a visitor clicks on the banner, he/she is redirected to your landing page. There should be a click tracking code, because it also creates a cookies, where PAP saves data about affiliate (or PAP remembers the IP address). When the customer makes a sale, then PAP loads data about affiliate from cookies or search the IP address. If the clicks are not tracked, PAP can not recognize, what affiliate should get a commission.
Check your plugins
If you are using some payment gateway, check the Plugins section out to see if there is a plugin for it. If there is one, check it out if it is activated, and configured properly.
Check your Fraud protection settings
The settings for Fraud protection can prevent some sale commissions from being saved. Check these settings out to see if all is set correctly.
