With dynamic templates, the private blog selection causes an inoperable display. Conversely, with Google+ Comments, enabling Google+ Comments disables the private blog (designated reader) selection - and vice versa, in the various Blogger dashboard pages.
The two interactions - and differing mutual exclusiveness - contribute to some interesting diagnostic sessions, in Blogger Help Forum: Get Help with an Issue.
Intriguingly enough, when one of the known limitations with private blogs is diagnosed, some blog owners may treat the limitation as a personal insult.

Private blogs do not publish blog newsfeeds. Dynamic templates require comments and posts newsfeeds, to generate the displays.
You can make a blog private - and you lose the "Dynamic Template" selection, in the dashboard Template page.

Google+ comments, and private blogs.
When Google+ is used, no access to the Blogger permissions database is available. Since Google+ Comments are (or can be) Google+ stream posts, Google+ Comments can only support public blogs.
If you enable Google+ Comments, you will see a warning in the Permissions wizard - and you'll have no ability to Edit "Blog Readers".

If the blog is private already, you'll similarly see a warning on the dashboard Google+ page.
Google+ Comments are unsupported on non-public blogs and blogs marked as containing adult content. Learn more
So Google+ Comments, and private blogs, are mutually exclusive, on the dashboard - though Dynamic Views and private blogs are not, with intriguing result.

And when the blog address is provided with the problem report, we can see the problem.
