I'm running version 4.0.1 (installer 1.0.2)
I noticed the problem while I was trying to grant users the right to suggest resources for the resources module. The 'Suggest new resource' button correctly appears but it only brings up a blank page (no warnings, nothing).
With higher rights (i.e. as Moderator or Admin) the button works just fine as well as the similar one 'Create new resource'. Within the admin-panel all rights seem to be set correctly (User can suggest; Admins can create) but again .. I can't even enable a specific user for the suggest-feature in the panel. Every attempt is prompted with "That user does not exist".
So far the only workaround would be to enable users to 'manage items' within resources - which is the same setting as for Admins.
