This got me on the path to finding the correct app to install. I ripped out what I had and started from scratch and now I'm just waiting for the site to be created (takes a while but I've got other fish to fry today)

Hi,
Do you want to use this Portal Template?

I tried to reproduce your situation but failed, this Portal Template always appear in my template although I use a new environment and fewer licenses.
Do you have any apps in your environment as described in the following document?
