如何清除 WordPress 缓存 2026

Seeing stale pages after updates usually means you cleared only one layer. Purge in the order below to avoid chasing ghosts.

我们如何核对文中步骤

发布前，若步骤依赖主机商，我们会在至少两家平台各走一遍；否则在同一环境隔日执行两次。我们记录控制台报错、不同地区的界面文案差异，并在厂商调整按钮位置后立即更新文案。路径与截图每季度抽检。涉及 DNS、SSL 或付款时，我们确认回滚/补救选项，并链接到官方文档以获取权威表述。

  1. 1

    Step 1: Purge page cache plugin

    LiteSpeed: Purge All; WP Rocket: Clear cache; W3 Total Cache: Empty all caches.

  2. 2

    Step 2: Purge host-level cache

    SiteGround SG Optimizer, Kinsta purge in MyKinsta, WP Engine purge EverCache from portal.

  3. 3

    Step 3: Purge CDN

    Cloudflare → Caching → Purge Everything (or single URL) after origin is correct.

  4. 4

    Step 4: Browser hard refresh

    Cmd/Ctrl+Shift+R to rule out local browser cache during QA.

  5. 5

    Step 5: Object cache / Redis

    If using Redis object cache, flush via plugin or host tool. otherwise menu changes may lag.

  6. 6

    Step 6: Confirm with curl

    curl -I your URL from terminal to verify headers reflect fresh cache status.

常见问题

Still stale?+
Check if a second invisible CDN (Jetpack, Sucuri) sits in front. purge there too.
Admin looks wrong but front OK?+
Disable admin caching features in optimisation plugins. never full-page cache wp-admin.
