  • GoodLike changed the title to Minecraft crashes on startup, says no JSON

The version you are using is no longer supported on this forum.

Please update to a modern version of Minecraft to receive support.

Currently supported versions are 1.19 (Latest) 1.18.2 (LTS) and 1.16.5 (grace period).

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.
