Can you share you issue website url? And maybe you can give someone here a admin permison to help you find what's going on.

    Second about sharing website URL. I'd generally advise against giving out admin perms unless you trust whoever it is

    Can you temporarily disable the extension that blocks fake/throwaway emails?

    SteveXu200512 You need to be reminded that you cannot speak Chinese alone outside the theme of the Chinese language pack. . . You need to attach an English translation. . . This is Flarum's forum rules.

    需要提醒您一下,在中文语言包主题外不能单独说中文。。。您需要附加英文翻译。。。这是Flarum 的论坛规则。我已经注册了您的论坛,我这就前去查看。

      So I've confirmed this, but if I may be honest, I think this is caused by an extension. Can you try disabling all extensions and trying again?

        Thanks, let me know when you do so so that I can check again
