创建组或子组后出错500

Question

我将Gitlab服务器升级到9.1，现在我无法创建新的组或子组。我明白了：

500
Whoops, something went wrong on our end.

我不知道该怎么做。我正确地重新配置gitlab并在尝试打开gitlab-rake gitlab时出现以下错误：检查日志：

/usr/bin/gitlab-rake error: could not load opt/gitlab/etc/gitlab-rails/gitlab-rails-rc

修改

尝试创建Wiki页面时也会发生同样的情况。但我能够创建新项目和新问题。

这是尝试创建Wiki页面后生产日志的输出：
