Accessing Level #1 page takes to membership option page

Hi!

I’ve been having this issue since the beginning and I’m not sure why.

I have a paid online course that consists of several pages. When my clients try to directly access one of those pages, the page that opens up is the membership option page (where the “buy” button is) and so, there is no way they can access the course (unless they directly type or click the log in page link)

I would like to know how I should do so whenever they want to access any of the Level #1 pages: the login page comes up, they fill in their username/password and then have access to that specific page.

I hope I have explained myself right… (English is not my mother language ;))

Thanks in advance!

Marta
