After an install of tiki 8.3, I don't see any way to attach files to wiki pages.
When I go to Admin -> Wiki -> Features I don't have the "Attachements" button.
In fact, my "Features" tab (see attached file) is quite different from the one described for instance at http://twbasics.tikiforsmarties.com/Using+Attachments. For instance, it doesn't have the "sandbox" feature ... and btw I don't see the "Flag Revision" tab either!
Any hint ?
