Confused by a fault of facebook?

[Sarthak]

Earlier,i sent a friend request to one of my friends.Later when i tried to open her profile on facebook,it couldn't open and the page broke.I thought that she has blocked me.But when I logged into my gmail account,there was a mail from facebook saying that she(the girl to whom i sent request) has confirmed my friend request.But on facebook,her profile couldn't open and the page is broken. I couldn't understand why i can't see her on facebook even if she had accepted my friend request. Please tell me if anyone could assist me. (It is not guaranteed that she has blocked me.) Thanks.
and if she has really blocked me,why will she block me even after accepting my friend request?
