I have a question with activate new site with WHMCS & Pro site


I have I followed all the plugin documentation and instruction to create a site https://premium.wpmudev.org/forums/topic/whmcs-provisioning-problem-dont-create-the-sites

But it still have an error :

Order Accept Encountered Problems
Product does not have an authorizing administrator defined. Please update the product module setting when I try to activated it.

Is it possible when completed the Paypal payment it will activated automatically ? Not manually ?
