After I got my "Access Denied" problem mostly solved (it's still happens occasionally), I tried updating the date setting on the date and time panel. I had set the separator to <space> and all it did was squeeze the month, day and year together: January122008. After that I just decided to work around that problem by changing it to a mm/dd/yyyy format which worked.
Unfortunately, it only looks right when I'm signed in as the administrator. When I sign in as a regular member the format is dd/mm/yyyy. Any idea why it is correct for the admin id and wrong for regular forum members?
