I can't log in with my user and password

[John Erick Cabrera]

First I had the message "No running instance of xfce-4 panel was found", then I rebooted my computer and the menu bar had disappeared, I rebooted again but now I try to loggin and password and the computer returns me to the menu of input user and password as if I had typed wrong my password.
