[Support request] Need location of ONE page to edit for final setup

Hi all,

I swear I have searched high and low, read everything I could find and searched this forum way too much. I am looking for what I assume would be a very common request and I also assumed easy to adjust. But I admit to being lost on this one.

I have the entire plugin and some addons all setup and working as I had hoped. It all works great and looks great except one small thing.

when I have a page protected and a non member clicks the link it takes them a system generated page with the URL ending in /members-only-area/ then there is a single line of text way up on the left hand corner of the page with the text stating:

You need to be logged in to view this content. Please Log In. Not a Member? Join Us

I was assuming maybe incorrectly that I could make this page more attractive and in keeping with the theme look and feel of the site. But I can’t for the life of me figure out where to do so. Is that something that is generated and I could use a short code to embed it in a page design I like?

I would really love to solve this last setup issue and make the site live, thank you to all those that take the time to answer. Much appreciated.
