我得到這個錯誤：

對一些用戶（不是全部）想看看時/我的/帳戶。

如果我嘗試地看到，用戶的個人資料作爲管理員，我得到：

我的（沒有受過教育）的猜測是，用戶錯過一個RSS的身份驗證令牌。

如果是這樣的話，你可以指點一些關於如何重新生成它的文檔嗎？

Answer 1

在字符串日期格式上postgresql和redmine之間的誤解似乎是根本原因（請參閱我對Declan Lynch答覆的評論）。

ALTER DATABASE redmine SET DATESTYLE=US; 

解決了我所有的問題。

Answer 2

您是否最近升級了Redmine？

只是爲了安全起見，我會建議運行升級後遷移以確保所有表都設置正確。

rake generate_session_store 
rake db:migrate RAILS_ENV=production 
rake db:migrate_plugins RAILS_ENV=production 
rake tmp:cache:clear 
rake tmp:sessions:clear 

一旦命令已經完成重新啓動Web服務器，看看是否有幫助。
