Blog Template Plugin

I have created a blog template from a blog set up just for that reason.
I created a new site and chose the template, but when I go to the site it
just shows our default old website from the main url address. The original
template blog works. I did check all the boxes in the advanced menu.
Any ideas - I need to create 70 student elearning portfolios to this spec.
I would share the urls but I have set privacy to requiring to be logged in.
Thanks
