Well, hello there! I recently installed minecraft forge for 1.8.9, world edit and optifine. Of course I put the world edit and OptiFine inside the mods folder. I opened the forge installer and installed forge. So then I tried launching Minecraft forge for 1.8.9 but it didn't work and I got a message saying ''ERROR, Game chrashed, An unexpected issue occurred and the game has crashed. We’re sorry for the inconvenience''. I already have forge with world edit and optifine for 1.12.2, and it works perfectly fine. Oh and by the way, the same problem occurred earlier when I tried to download forge and world edit for 1.14. Please help me!
