I'm really confused

Ok I have four questions:
1. Am I in trouble?
2. Did I do something wrong?
3. Am I getting banned?
4. Is it because of my age? Am I too young to be a part of this site, I know you don't want kids in here putting in unneeded pages (Halo, Star Trek, etc.) But I didn't think I was causing any sort of problem?

I'm asking because I have no idea what's going on. I went in today to edit my profile page, and it says ''You don't have permission to do this action", and the same things to every page I go to, I thought it was a glitch or something. I went and asked this before a while ago and my thread got deleted. So yeah, can a Mod or Admin tell me what the heck is going on because I am really confused.
