Only Super Admin sees the settings menu in Q&A plugin

When I enable this plugin on a site in a multisite network only the super admin can access the settings part of the admin menu. The site admin only sees the other Q&A admin options.

Additionally clicking the Answer and Add new answer button in the admin panel it produces a dead page with:
Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.

This happens on any theme I have tried. eg Almost Spring, Edublog etc.

I have only just joined on 12 months and found fairly long existing bugs and/or problems with Newsletter plugin not allowing SSL smtp/pop logins and now this Q&A one too. I need to feel things are more loved here, am I wrong?
