隐藏错误：网站遇到意外错误。请稍后再试

Question

我在浏览器左下方的所有时间都收到了此消息，即使该网站已全部正常工作。这对用户来说有点烦人。我试图用CSS隐藏它，但似乎不可能。

你们是否知道如何隐藏错误讯息？这是来自日志文件的错误：

这似乎是一般错误，并且要解决它，您应该尝试从代码调试/跟踪问题。我从你的问题中得到的是你想要消除这个错误并且现在为用户显示，如果这是在生产环境中，你应该禁止向前端报告错误，这可以在D8中通过转到admin/config/development/logging并选择“要显示的错误消息”并保存您的配置。之后，您可以调试并跟踪此错误。

我希望这可以帮助你。
