详情介绍:
LumenCache implements a RAM-first full-page cache with a WordPress
advanced-cache.php drop-in. On a cache HIT, the drop-in serves complete HTML
before the normal WordPress bootstrap and database queries. This early-response
path reduces application-layer work and keeps repeat page requests fast across
Nginx, Apache, and LiteSpeed.
The cache is designed to fail open when its storage layer is unavailable, so a
cache connection problem does not take the WordPress site offline.
常见问题:
Getting a 502 Bad Gateway on Nginx after activating or during WooCommerce use?
Nginx has a default fastcgi_buffer_size of only 4KB–8KB. When combining rich caching headers with WooCommerce session cookies, the upstream response header exceeds this limit. Nginx immediately terminates the connection with:
upstream sent too big header while reading response header from upstream, resulting in an instant 502 Bad Gateway error.
To resolve this, add the following FastCGI and proxy buffer directives to your Nginx configuration (within the http {}, server {}, or PHP location block):
fastcgi_buffer_size 32k;
fastcgi_buffers 16 16k;
fastcgi_busy_buffers_size 32k;
proxy_buffer_size 32k;
proxy_buffers 16 16k;
proxy_busy_buffers_size 32k;
After adding these directives, test and reload Nginx:
nginx -t && systemctl reload nginx
Why are 0 pages cached?
Two common causes:
- Nginx config not applied — visit Server Setup and paste the config blocks.
- WooCommerce session cookie — fixed in v1.1.0. Previous versions bypassed
the cache for all visitors on WooCommerce sites due to the always-present
wp_woocommerce_session_*cookie.
Why can key salting affect server-level caching?
When LUMENCACHE_CACHE_SALT is set, PHP stores keys as SHA-256 hashes. A
server-level configuration must use the same key strategy or it will produce
cache misses. Disable the salt for a plain-key configuration, or use the
compatible hashed-key server template.
Does LumenCache work with LiteSpeed?
Yes. LiteSpeed supports Apache-compatible .htaccess rewrites. LumenCache uses
the Apache proxy mode on LiteSpeed. For better performance, ask your host
which in-memory cache acceleration options are available.
Can I still use wp-config.php constants?
Yes — constants always take precedence over admin settings. If you define a constant, the corresponding field in the Settings tab is shown locked (read-only).

1.7.5 (October 6, 2026)
- REST API GUEST HYDRATION RESILIENCY: Hardened
/wp-json/lumencache/v1/user-stateto gracefully isolate guest-safe keys (cart-count,cart-total) when unauthenticated requests contain mixed-key requests (such as headers rendering both cart widgets and member greetings), preventing 403 authorization rejections from breaking guest cart hydration. - LCU LMS & SENSEI COURSE PROGRESSION: Added native student course progress resolution for Light & Composition University's LMS (

- TAB CONTINUITY & FORM REDIRECTION: Injected explicit
from_tabhidden inputs across Settings, Cache Controls (Flush All, Purge URL), and Server Setup action forms, guaranteeing that all form submissions and admin-post actions reliably redirect administrators back to their active working tab. - HTACCESS ERROR RESILIENCY: Hardened
handle_htaccess_write()to validateWP_Errorreturn states fromHtaccess::write_rules(), passing distinct error notices with diagnostic messages instead of reporting false positive success on filesystem permission failures; added distincthtaccess=removedhandling for rule deletions. - APACHE & LITESPEED SERVER SETUP CARD: Introduced dedicated "Apache / LiteSpeed Direct RAM Proxy (.htaccess)" management card on the Server Setup tab for Apache and LiteSpeed environments, providing real-time deployment status, one-click rule write/remove controls, and a copyable rewrite rules block.
