隱藏錯誤：網站遇到意外錯誤。請稍後再試

Question

我在瀏覽器左下方的所有時間都收到了此消息，即使該網站已全部正常工作。這對用戶來說有點煩人。我試圖用CSS隱藏它，但似乎不可能。

你們是否知道如何隱藏錯誤訊息？這是來自日誌文件的錯誤：

這似乎是一般錯誤，並且要解決它，您應該嘗試從代碼調試/跟蹤問題。我從你的問題中得到的是你想要消除這個錯誤並且現在爲用戶顯示，如果這是在生產環境中，你應該禁止向前端報告錯誤，這可以在D8中通過轉到admin/config/development/logging並選擇「要顯示的錯誤消息」並保存您的配置。之後，您可以調試並跟蹤此錯誤。

我希望這可以幫助你。
