CrazyCrates需要更新https://www.spigotmc.org/resources/crazy-crates.17599/

本帖最后由 Yuri南城 于 2022-3-29 12:04 编辑

尽量使用插件最新版，且您的 PlaceholderAPI 是什么版本？看起来 EZPlaceholderHook 在插件高版本已经被移除。

于是您有两种方法：更新 CrazyCrates 或 降级 PlaceholderAPI。
当然，建议时刻保持插件最新稳定版。

总结：楼上是正确的。
（个人审题错误导致我胡编乱造一下

我服务器是1.8版本 cc抽奖插件版本最高到v1.8.3啊

PlaceholderAPI-2.10.9

https://github.com/Crazy-Crew/Crazy-Crates/releases/tag/v1.10.3
1.8 可以使用 v1.10.2

另外建议更新 PlaceholderAPI 至最新版 2.11.1

请尝试使用v1.10.2版本

作者原话“如果您希望在MC 1.8.8-1.17.1上使用CC，请使用CC v1.10.2.”
https://cowtransfer.com/s/c98b7033e58d4f(1.8.8的插件1.8应该也兼容的)

站内的没更新

换上v1.10.3之后更惨了 加载都加载不了
