Cloner plugin not working

I am trying to clone one of my template sites. The first time I tried there was an error listed but it continued and created the new site. When I tried adding existing users the dropdown did not display any roles on the new site. All of my existing sites still have this function including the template. I tried again and the process stops with the following message: We're setting up your new blog. Please wait...
An error has occured.

I have granted support access already if you can take a look.

Thanks,
Jeremy
