Problem with Customizing Profile

[MortenNS]

I have this problem that when I go to my profile and try to customize it, it won't work and this pops up.

MortenNS, you do not have permission to access this page. This could be due to one of several reasons:

1. Your user account may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system?
2. If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation.

When I read this I was like:

1. "Wtf? I'm not trying to edit someones profile, I'm trying to edit my own!"

2. "Who the **** posts by clicking customize profile?"
