Link To Existing Page Treated As Protected Content

I am trying to put a link to an existing page on my website (

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 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.
