It works, at least now.
WTF? When it was working (now te bug is still there), I was in a new account I created, in my DarthVater account (is in Default). Then, with tonibm (Admins), I had the bug. I'm very confused. Maybe, is something relevant to change gamemode (creative to survival), but I don't know.
After that, with a new account, the error wasn't there. It's very strange, with new accounts on the server there isn't the error but with my admin account, the error is there.
