cape menu keybinding is not "c" if ur using optifine since optifine use keybinding "c" as zoom. u can change it in settings>controls. and no, the cape menu dont crash on me, it works fine. but the problem is since u said 1.8.9 cape menu no longer exist and we use the /setcape command, it dosent work, not at all. it said command dont exist. i told u this in issues before, the "url problem". so i guess, not the mod problem, this website problem. i know that cuz i look the url properly. it said capes instead of cape-gallery. so pls fix this, hope u can do it
