为 Discourse 配置 Twitter 登录和丰富的嵌入

[Lilly]

可能是因为托管站点和 Meta 最近已修复

Twitter links are no longer oneboxing

I just updated the API keys used on meta, and rebuilt the OP. Tweets now are embedded correctly here (and for clients in our hosting). The issues raised by the OP still apply to self-hosters though. One alternative option here is to load native Twitter embeds, see this theme component.
