yes, sorry, that's what I wanted to say.
It appears when you configure a profile without a secondary group but with Force member to use selected permission sets... (and of course the selected set allows an access to the gallery).
For example, here is a profile configuration of a member having this problem :
She is a moderator, without secondary group. I asked the use of the permission sets "SQF" (which allow a gallery access), but she can't see the gallery.
Thanks a lot.
