Http Authenticated PhPBB Feed not working

Hello

I’ve been trying to set up a feed from the forum located at
Loreseekers.eu/forum
with http authentication so that only members can see content in from the members section and so on.

I’ve made a support thread in the PhPBB support forum but as far as they’ve been able to tell the problem doesn’t lie withing the PhPBB client.

So I was wondering if there’s something within the WordPress config that I have to change or if there is perhaps a widget I need in order for this to work.

more information about my problem can be read in the PhPBB support thread mentioned earlier
