In the legacy version 1.x of the plugin, CloudBees was using
go.pardot.com to track the users registrations when the plugin was available for free. With the version 2.x, the Advisor service is accessible only for CloudBees customers, this notification to Pardot is thus useless and not used.
Minimum version of Jenkins core is now 2.60.3
If after saving the Advisor configuration you reach a
go.pardot.com url with a message
"Cannot find success page to redirect to. Please use your browser back button." you can just discard it and use your browser back button to come back to your instance (The configuration was correctly saved).
