Problem Description

Issue

My Minecraft server won’t start because your AMP panel is automatically adding -o to the startup command. Paper and Spigot 1.21.1 don’t support -o, they use --online -mode instead. Please remove the -o flag from the startup command or give me direct access to edit it.

Reproduction Steps

  • going through every document looking for the -o
  • Created a Minecraft server on Hostinger using the AMP panel and uploaded a Paper 1.21.1 jar renamed to minecraft_server.jar
  • Attempted to start the server through the AMP panel
  • Server crashes within 5 seconds — checked logs/latest.log and found this error: joptsimple.UnrecognizedOptionException: o is not a recognized option
