uploading my server, look and help me please.

Go to your world database
search table command
find line:
server info    0 Syntax: .server info

Display server version and the number of connected players.
and change the security to 1, so only players with gm level 1 can use it.

Or just use this in the console:
UPDATE `command` SET `security`='1' WHERE (`name`='server info');

Thank you so much smile
