Hi Geoff,
I instantiated the Project Dashboard template and I had no issues. Also I instantiated the Single Project template and same no issues.
My site structure looks like this:
http://machine:1234/prj This is the projects dashboard
Under this site I instantiated the Single Project and the sctructure is the following:
http://machine:1234/prj/single
One thing I want to point is that you need to have proper permissions to see/work with the template.
Please note that there are some security instructions to follow in order to make them work.
Please let me know how it goes.
PS
The templates we distribute with the product are for learning purposes however we have customers that use them in production and also customers that developed more features around these templates to adapt them better to their business needs.
