This documentation will show you how you can edit your server properties on your minecraft server.
<5>How to edit server properties.
Step 1 Go to your panel at mixmlhosting.pro and login, if this your first time logging in, make sure to check your email and you'll have a button to setup your account. After that, login with your setup credentials!
Step 2 Once you are on the game panel, go to the "Your Servers" tab and click on your server!
Step 3 Then go to the "File Manager" tab (Or connect to it via SFTP)
Step 4 And then click on the
server.properties file in the /home/ folder
You can edit via the text file that pops up (Notepad++ is quite good for files like these if your using an external connection app)
