DDNS menu not showing if error in the configuration

Hi everybody!
I added a DDNS but made an error in the host and now the menu won't appear. Is there a way to disable and erase my entry via terminal?
Lan setup stays blank while is stays forever on the "execution command , please wait" without letting me the ability to change any value. :pound
