I know how to use Putty, I know what command line in linux and Putty is, but i dont know if xenforo have it own command line. Many software or games or interfaces have a command line, that is why I hace a mess if people just say " command line ".
Ok I find the problem, I work with 2 admin accounts, one have not all permisions, so is that. My bad, sorry for take a bit of your time and thanks for show me where is it ;)
