All those errors mean is that those commands (help, version, serversidename, loc, flag, and si) don't have a required level to be used and it's defaulting the level to "everyone who's logged in". This is only a problem if you are running a Legit, Custom-Legit, or Semi-Legit server and don't want people to use commands like si or flag. Normally I just ignore them but if you want, you can add the following lines to the bottom of your 'addon.ini' file to get rid of those errors (note this won't actually change who can/cannot use them, it will just remove the error message).
addon.ini
Code:
!help=0
!version=0
!serversidename=0
!loc=0
!flag=0
!si=0
