Hi,
If you don't know how to edit your worldserver.conf and authserver.conf, do check the guide below.
1) Download the SSH + FTP client named Bitvise on this link -> https://www.bitvise.com/ssh-client-download
2) Once downloaded and installed, create your profile and enter the root login details that we've sent you. Make sure to save this profile so you won't have to input again.
3) Input /home/root/server/etc on the remote site textfield and you should be redirected to the location of the configuration files then edit accordingly.
4) Once done, you should restart your core via terminal for your changes to take effect. There are 2 ways to restart your core.
4.1) Typing via GM character ".server restart 300" (where 300 is 300 seconds)
This is the easiest and fastest way to restart your worldserver. (Do note, authserver will only be restarted not world)
4.2) Or manually restart it via ssh terminal, do refer on this link ---> Click Me
