Head over to the Game Panel and stop your server.
Download the SkinsRestorer -plugin/mod on your computer and after it has installed, navigate to the plugins folder (or mods folder if your server is modded) in the Files tab of the game panel. Upload the downloaded file there.
Done! You can now start the server and the skins will appear.
Congratulations, you've successfully enabled skins on your cracked server. If you have any issues or concerns, please contact us through the ticket system.
