Hi all,
i'm running a 3.1 with xmlui-mirage, This system has running for just 4 days now.
I just realise now that if i click an item (as guest or an identified user or as an admin) the 'View Item' page only shows: 

This item appears in the following Collection(s)

nothing more,
as in my previous dspace version (1.7 xmlui-manakin) it shows several metadata such as title, author, abstract, ... even its bitstream file.

what have i done wrong?

best regards,
