On our site, we have 4 stacks defined. One is a small scrap of HTML and an auto-nav for our sidebar. Guests don't have any trouble seeing that. The other 3 are groups of individual blocks of bios of different persons. For some reason guests can't see these, only signed-in users. I also created a new block of a page list and a scrap of HTML and guests could not see that either.

We're using advanced permissions and in all cases "guest" has VIEW on the page and VIEW BLOCK on the block/stack. I even looked at all the block permissions in the stack and they all have VIEW for "guest".

Any thoughts of where to look next? We're a bit stumped here.
Thanks!

EDIT - The missing solution was that we needed to add VIEW VERSIONS for "guest" at the page level and not just VIEW. Hope this helps someone.
