Well, I upgraded from 1.4.x to 1.5.18.
Things seemd OK. I can see the categories, then the album's thumbs and finally the thumbs
inside the albums. But when I am a normal visitor whemn I click to some thumb in an album I get
the message "You must login view this page". If at this level I login as an administrator I can see tha "normal" and the "big" pictures, so they are there.
There is no password set on the albums, I mean the corresponding item is not checked.
Any help?

Alternatively you can set the permissions for each group in the groups manager.
Moving topic from install to permissions board.
