Weird permission issue

[chlarsen]

Dear All,
First of all, thanks a lot for this nifty little, yet ever so essential app.
What I would like to achieve, look reasonable simple, but I have had some issues:
I have a landing page (done with Botostrap Caerousel, using Mezzanine's dedicated index.html) that has links to several pages. I want that these pages that are linked to can be viewed by all users (anonymous access), but edited only by page-specific groups, which is why I used the mezzanine_page_auth app.
So, when a logged-in member of the group that has edit access to a link clicks on the link that appears on the landing page, all is fine.
However, anonymous users find themselves with a white page of death (log says: 401, access denied), even though they are supposed to have read access.
What am I doing wrong?
Thank you so much for any pointers!
Chris
