Launching Forge in Support & Bug Reports Posted September 19, 2017 The mod quark does not wish to run in Minecraft version Minecraft 1.8. You will have to remove it to play. Perhaps that is the problem. I think you need to remove the quark mod as the version it was compiled for is different. Or so it gives the impression. I don't know about a best version as I think the word "best" is considered subjective in many places by many people and touching it is probably a hot button subject among players, but maybe you could try the latest minecraft version for which a stable version of forge exists.
