I can't tell how many mods you have, but it looks like you have two versions of jei installed, or something else is using the id JEI (which would be absurd to me because JustEnoughItems is a very popular mod). I would suggest searching your mods folder for jei, and delete any duplicates, or if there are no duplicates, delete and reinstall the mod.
