我在阿里云服务器上安装好了Flarum，安装了一些插件并设置了SMTP。而后当我测试用户注册的时候，却出现了下图所示的情况：但用户实际上是注册了的，邮件也发出去了，这种情况该怎么解决呢？我的环境是PHP7.2 ,MySQL 5.6,Nginx。网站地址：地址

littlemodesty 可以在根目录 config.php 开启 DEBUG 模式，注册的时候可以看到报错详情

Flarum安装后用户注册出现问题

littlemodesty

Golden 我开启了DEBUG模式，出现了题为”200“的错误提示：

是邮件插件出现了问题吗？

Golden

littlemodesty Pretty Mail 插件出问题了，关掉注册一次试试问题还存在不。有没有添加我共享出来的模板代码？

littlemodesty

Golden 关掉之后就没有问题了。没有添加你共享出来的模板代码，就是用的默认的，是必须要添加才会不出现问题吗？

Golden

littlemodesty 跟模板没关系

littlemodesty

Golden 额，所以不能再启用Pretty Mail了吗？

Golden

littlemodesty 重装一下这个插件，然后 php flarum cache:clear 清理缓存，再开启插件看看

littlemodesty

Golden 好的，谢谢大佬！

大佬，我的论坛在一次性开启几十个插件后发现不能注册了，按照您上面说的，我在那个文件夹里把那个改成TRUE后，出现了一个500的链接，以上是链接内显示的内容。我尝试把谷歌验证，密码显示的插件都关闭了也不行，按照您上面说的，我把pretty-mail这个插件卸载了并且清理了缓存，但还是不行🙏。
希望大佬能帮我看一下，这确实不太好意思，但我已经尝试了很多次，真的不知道是哪里出问题了😭

我使用邮件发了一条邮件是可以正常发送的，不知道是出了什么问题
