Problème de Démarrage de Forge 1.10.2

[Yuksay]

Bonjour,
cela fait plusieurs jours que j'ai un problème lors du démarage de minecraft (plus précisément la version minecraft 1.10.2 avec forge):

Chaque fois que je lance minecraft forge (peut unporte la version du jeu)
le message d'erreur suivant s'affiche :

---- Minecraft Crash Report ----

WARNING: coremods are present:
Contact their authors BEFORE contacting forge

// Uh... Did I do that?

Bonjour,
Retires optifine, tu as une version incompatible avec ta version de forge.
