I don't think DirectAdmin has anything to do with WordPress.
I think it's about installation path but I'm not sure. That's why I want to ask.
cd /usr/local/directadmin/scripts
./set_permissions.sh domaindir example.com
(replace example.com with real domain)
Or set the user home
cd /usr/local/directadmin/scripts
./set_permissions.sh set_user_home $USER
(replace $USER with real username)
Man, seriously.... "Server Admins" these days are jokes.......
For some this will be the case.Edit: I'm sorry if this sounded harsh but
