    背景

    网站突然出现 Briefly Unavailable For Scheduled Maintenance （因计划维护暂时无法使用。请稍后再回来查看）

    如果这个状态已经过去了五分钟左右，你仍然在屏幕上看到“由于定期维护，暂时无法使用。请稍后再查看”，而不是你的网站。

    这意味着您的网站遇到了维护模式错误，目前处于停滞状态。因此，您和您的网站访问者目前都无法访问该网站。

    但别担心！这只是WordPress 的日常事务。您无需进行大规模的技术工作即可恢复您的网站。

    在本文中，我们将研究WordPress 维护模式错误的主要原因，向您展示如何修复此问题，并分享一些技巧以帮助您避免将来出现同样的问题。

    是什么导致 WordPress 出现“由于计划维护而暂时不可用”错误？

    当 WordPress 执行更新时，它会进入维护模式。在此期间，会在站点的根目录中创建一个临时的 .maintenance 文件，该文件会通知您和网站访问者，站点正在进行重要更新，很快就会恢复。

    这本身不会破坏您的网站。这只是 WordPress 在更新时替换或修改根文件夹中的核心文件时设置的一项安全措施。如果实时执行，这些操作可能会破坏您网站的功能。

    WordPress 网站通常会处于维护模式几秒钟到几分钟（几乎察觉不到！）。应用更新后，WordPress 会删除 .maintenance 文件，将网站从维护模式中移除，并恢复常规用户访问权限。

    到目前为止，一切都按预期进行。没有什么异常。

    但是，意外错误（例如文件系统错误、服务器超时、互联网问题、更新权限问题或插件/主题冲突错误）可能会中断更新过程。

    问题就从这里开始。不完整的更新会影响根文件夹，导致 WordPress 无法删除 .maintenance 文件。因此您的网站永远处于维护模式。

    在我们仔细研究如何修复以下错误之前，这里列出了导致网站处于维护模式的最常见因素：

    • 在更新期间关闭浏览器窗口。
    • 同时更新多个插件。
    • 由于托管服务器响应缓慢或内存不足导致更新脚本超时。
    • 更新过程中互联网连接断开，导致更新中断或延长。

    如何解决 Briefly Unavailable For Scheduled Maintenance

    使用 FTP工具登录您的 WordPress 服务器后台，找到并删除 .maintenance 文件，刷新页面
