Abusing my Blog.

...I'm having a little problem:
I would like to edit my profile, but everytime I click on "My account" - or want to look on someones profile - I get a blank page, saying "Please register.".

Thanks guys, I'm desperate for help.


( I actually wanted to introduce myself, but I just don't have much to tell, I'm quite shy. D:
oh and please excuse me for my english)
