Link To Existing Page Treated As Protected Content

I am trying to put a link to an existing page on my website (http://www.noanettrader.com/disclaimer).

This page is accessible to all when directly clicked on from the main menu or if navigated to.

However, when a visitor to the website clicks on a link to this page from another page (bottom of http://www.noanettrader.com/trading-record/ for example), the link does not work because the membership plugin treats it as protected content for some reason.

Any help with this would be greatly appreciated.
