很感谢你的热心解答，解决了我的问题，但是还是出现新的问题了，点击登录出现这样的提示 [image]

管理员只能使用邮件进行登录，没有其他方式可以登录

我现在已经重装了，感谢你的耐心解答，谢谢。

What's causing the login issue?

If not, perhaps this?

The Discourse ID cannot be used after changing the forum domain

Regenerating the credentials didn’t work, but the method in that post did. Thank you for finding it for me.

./launcher enter app
rails c
SiteSetting.discourse_id_client_id = ""
SiteSetting.discourse_id_client_secret = ""
