Nevermind I figured it out! But thank you so much!

Where do I go to backups?

So I was trying to change my forge version to 1.13.2, it was a beta version and i went on the world and it was fine but optifine didn't work or world edit so i just went back to 1.8.9 now it says this when I try to open up the world. And when I open it up on 1.13.2 NO FORGE it works, and then I open it on 1.8.9 iwth Optifine, Bspks Coe,ArmorStatusHUD,StatusEffectHUD, and WorldEdit, it does not work, which doesn't really make sense? ---- Minecraft Crash Report ---- WARNING: coremods are present: Contact their authors BEFORE contacting forge // Shall we play a game?
