Prism Launcher​

Prism Launcher makes it extremely easy to access and upload your logs directly from the launcher.

Tips for Getting Help​

When asking for help in Discord or forums:

  1. Always include the mclo.gs link - Don't paste raw logs into chat
  2. Describe what happened - What were you doing when the issue occurred?
  3. Mention any recent changes - Did you add/remove mods, update anything?
  4. Include your launcher - Let people know which launcher you're using
  5. Specify the modpack version - If applicable

Example help request:

"My game crashed when I opened a chest. I'm using Prism Launcher with Homestead 1.2.6. Here's my log: https://mclo.gs/xxxxx"

Troubleshooting​

"My latest.log is empty"​

  • Try looking at debug.log instead
  • Make sure you actually launched the game (logs are created on launch)

"I can't find the logs folder"​

  • Enable "Show hidden files" in your file explorer
  • The .minecraft folder is hidden by default on some systems

"mclo.gs says the log is too large"​

  • Try uploading just the last portion of the log (the most recent entries)
  • Look for the crash report file in crash-reports folder instead

"The log doesn't show my crash"​

  • If the game crashed hard, the crash might not have been written to latest.log
  • Check the crash-reports folder for a dedicated crash report file
