backwardsd on "under construction"

I recently activated the "under construction" plugin, and it works just fine. The problem is, I can't see the site that I'm editing. According to the description if one is logged in they can see everything. I can't see anything. Is there something I'm not getting here?

Which plugin are you using for under construction?
I have used some under construction plugins that I was able to see the site while I was logged in as an administrator.

It's literally called "under construction". I can switch if there's a recommendation.

"WP Maintenance Mode"--I use this one frequently.

Ok. Thanks.
