Articles Permission denied

Hi to all:

I’m fairly new to RT, I have all my queues setup and working fine. I would
like to create aome articles (which I’ve heard i can create to attach to
tickets when closed with specific instructions for example). When creating
an article, even as root (have tried with user with full privileges as
well) and when I click create artcle, i receive immediately an Permissoon
Denied. Obviously i am missing something, can someone shed some light on
this.
Thanks in advanced
Richard
