Code:
wizinmemberrooms [yes|no]
"wizinmemberrooms" controls whether wizards may enter closed member
rooms and member rooms with a password. (In the default server, only
gods may enter such rooms.) Note that a server "feature" may cause the
message, "Sorry, the room is closed." to display for the wizard even
though entry has been permitted. If wizinmemberrooms is enabled, all
users will receive the message, "NOTE: Wizards may enter closed and
passworded member rooms on this server."
You will have to turn off this setting by editing plugall.txt and changing yes to no. If your server is hosted remotely you may have to download the file through FTP. Then make the changes, save them, then upload and overwrite the file. After the file is changed you may use the command `plugall reload or restart the server to active the setting.
