blog templates on register page aren't working

On the registration page to create a new subsite, the New Blog Templates are not working. I normally had the preview option selected where a demo of each template could be viewed by the visitor, but now it kicked me out of the registration process. So, I went into the settings for that plugin and changed it view only a screenshot image of each template, but now it doesn't allow me to select any template other than the default.

I did the updates in the past couple weeks--I think both for Prosites and New Blog Templates, so something changed.

Can you please take a look and see what's wrong?

I am enabling access from my dashboard.

Thanks, Joe.
