Mary, thank you so much!
Yes, the lesson on Water is exactly what we have.
The guest access was enabled as per the documentation: course administration ->Users -> Enrolment methods ->Guest access and then setting it to Yes.
OK, What I am saying is that if I go to the Lesson Administration as admin user, I select the Edit Tab AND the Expand tab, then each page has a description below it, and for most of the pages this is "content". The Guest user can see all the pages that are named as "content", but is not able to see the one that is named "essay", although they are taken into it.
I have taken a screenshot of what I mean and I attach it. So the user can see the page that is labeled content, i.e. Live 1, but not Live 2.
You are welcome to try this as a guest user. The URL is: http://svp-b-attitudelife.online/ you can access is as guest. If you select the first module - personal development, and then the first topic "who, what, how and why", you will be able to see the first 7 pages, but you will get a blank screen on page 8 (live 2), and you will not be able to move along.
Thanks for your help!
