Please check out the following article on the file format
Yours line looks like this;
user1,password1,User Number 1 (Test),Site Administrator,System,yes,firstname.lastname@example.org
I think that it is the Site Administrator which is the issue, and the line should look like this;
user1,password1,User Number 1 (Test),Interactor,Site,yes,email@example.com
Hope this works
Thank you very much - I really do appreciate your help. I am also a bit confused, though. The documentation that we both referenced says "Site roles include Site Administrator, Publisher, Interactor, or Viewer, and a couple of others..." I thus don't understand why Interactor would work in lieu of Site Administrator.
Thank you very much for your help and guidance. I sincerely appreciate it, and hope that your week is off to a great start!
