As of two days ago, I can login or register as a new User ONLY if my Admin uname is actively logged in. If my admin name is logged out, I will get the "Access Denied .. you are trying to access a restricted area" screen, every time I try to login as a user or register as a new user. I cannot figure this out.

I've changed all pemissions on all files to Read/Write, in case that was the issue. This is a new problem, it was working fine and something happened, but I don't know what. I'm using Nuke6.0 with PHPBB2.0.6 The site is still being developed on my local machine, so i have no URL to post.

Any ideas on a direction as to what file to look at (or replace)?
Thanks for your time,
