我在我的 Discourse 站点上遇到了问题：hub.youthpowercoalition.org
有些人无法注册。我目前只进行了有限的测试，但这可能仅适用于包含数字的电子邮件？
错误消息：“出错了，也许用户名或电子邮件已注册。尝试使用忘记密码链接。”
我们肯定使用的是尚未注册的电子邮件。
我们该如何排查此问题？
我尝试在电子邮件中强制加入一些数字，但无论是否包含数字，注册均失败。
请检查账户或数据库日志区域是否有任何问题（仅您可访问）：https://hub.youthpowercoalition.org/logs
我之前不知道有这个区域，谢谢！
以下是最近日志的截图。
以下是仅来自周一的日志详情
