I have a related list of files "AttachedContentDocuments" on a VF page (using the tag), which is accessed through a force.com site. This page works as expected for the logged in user. But when accessed over the site (i.e: for a guest user) it returns the "Authorization Required" error page.
I am aware that this typically occurs because of a permission issue. But I am unable to locate the permission required for this to work.
Waiting for suggestions.
