[xwiki-users] No create wiki menu in XWiki 5.4.3

Hello, Just migrated from 4.5.2 to 5.4.3, and it worked perfectly except some "issues" (or misunderstandings) : - My user is in an admin group with admin and PR rights, and I've set it also (on the group) the "create wiki" right. Still, when logged in, I don't have any "wiki" item in the "Add" menu (only usual space, page, ...). I'm sure I'm missing something obvious but can't find it. - I show the Blog in a gadget of the Dashboard. Weirdly, "permalinks" correctly point to each blog entry, but the link from page title points to a create action (though it points apparently to exact same url as permalink except for the "create" action). The same for the buttons on right side of each blog subject (create/delete/....) Thanks, Jeremie
