修复步骤 #

• 替换受损核心文件：
  下载与当前WordPress版本完全一致的安装包，解压后找到wp-includes/blocks.php和wp-includes/blocks/navigation.php文件，用FTP或服务器文件管理器上传覆盖对应文件（操作前务必备份原文件）。核心文件损坏是这类错误的常见诱因，替换后多数情况可解决问题。

• 排查主题/插件冲突：
  通过FTP重命名wp-content/themes下的当前主题文件夹（例如改为themes-old），强制WordPress切换到默认主题；再重命名wp-content/plugins文件夹为plugins-old，禁用所有插件。若网站恢复正常，再逐个恢复主题和插件，定位引发问题的对象后进行更新或移除。

• 清除所有缓存：
  清空服务器缓存、CDN缓存，以及WordPress缓存插件的缓存（如有）。缓存残留可能导致错误状态持续，即使文件已修复。

• 升级至最新稳定版WordPress：
  若当前使用旧版本WordPress，该错误可能是已知bug，升级到最新稳定版可修复这类兼容性问题。
