1. LiteSpeed Cache Plugin (LSCWP) Settings

• Install & activate LiteSpeed Cache plugin.
• In Cache → Cache, enable:
  • Enable Cache: ON
  • Cache Logged-in Users: OFF (unless you run a membership site)
  • Cache Mobile: ON
• In Cache → Purge, keep defaults. LiteSpeed will purge local cache when you update posts/pages.

---

2. Turn Off QUIC.cloud CDN

• In LSCWP → General, set Use QUIC.cloud CDN → OFF.
• That way, you’re not routing traffic through both Cloudflare and QUIC.cloud (which can break things).

---

3. Still Use QUIC.cloud for Optimization (Optional, Recommended)

Even if you don’t use its CDN, you can still use QUIC.cloud for:

• Image Optimization (compresses images in background, WebP/AVIF support).
• Critical CSS & LQIP (improves Core Web Vitals).

To do this:

• Go to LiteSpeed Cache → General → Server IP → set it.
• Then in LiteSpeed Cache → Image Optimization, request a QUIC.cloud API key.
• Make sure General → Domain Key is active.

⚡ Important: This won’t interfere with Cloudflare, since it only processes resources, not live traffic.

---

4. Cloudflare Settings (the right way)

• In Cloudflare DNS, keep your domain orange-clouded (proxied) → you get CDN, security, SSL.
• In Cloudflare Caching → Configuration:
  • Set Caching Level → Standard.
  • Browser Cache TTL → Respect Existing Headers.
  • Page Rule (optional, but recommended): *example.com/wp-admin/* Cache Level: Bypass (Prevents Cloudflare from caching your WordPress dashboard.)
• In Cloudflare Speed → Optimization:
  • Turn Rocket Loader OFF (it breaks WordPress/LiteSpeed sometimes).
  • Don’t use Cloudflare’s “Auto Minify” if you already use LSCWP’s minify. Let one system handle it.

---

5. LiteSpeed Cache + Cloudflare Sync

• In LiteSpeed Cache → CDN, enable Cloudflare API.
• Enter your Cloudflare API token (with “Zone: Cache Purge” permission).
• This way, when LiteSpeed purges a page, Cloudflare will also purge it. ✅ No stale content.

---

🚀 Final Result

• LiteSpeed Cache: Handles smart WordPress page caching on your server.
• QUIC.cloud (partial use): Optional for image optimization + CSS only.
• Cloudflare: CDN, SSL, DDoS protection, global cache.
• No double-CDN conflicts (QUIC.cloud CDN is off).

---

Here’s how to set up Cloudflare + LiteSpeed Cache plugin (LSCWP) so they sync perfectly:

---

🔧 Step 1: Create a Cloudflare API Token for LiteSpeed Cache

1. Log in to Cloudflare dashboard.
2. Go to My Profile → API Tokens → Create Token.
3. Use the “Custom Token” option.
4. Permissions to grant:
   • Zone → Cache Purge → Edit
   • (Optional but useful) Zone → Settings → Read
5. Zone Resources:
   • Select Include → Specific Zone → [yourdomain.com]
6. Save the token — copy it (you won’t see it again).

---

🔧 Step 2: Add Cloudflare Token to LiteSpeed Cache

1. In WordPress admin, go to LiteSpeed Cache → CDN.
2. Enable Cloudflare API.
3. Enter:
   • Email Address: your Cloudflare account email.
   • Global API Key (not recommended) OR API Token (recommended).
   • Domain: yourdomain.com
4. Save settings.

Now, when LiteSpeed purges a page/post, Cloudflare will instantly purge the cached copy too — no more stale content stuck at Cloudflare’s edge. ✅

---

🔧 Step 3: Cloudflare Page Rules (Prevent WP Admin Caching)

In Cloudflare, go to Rules → Page Rules → Create Page Rule. Add these:

1. For WordPress Dashboard: *example.com/wp-admin/*
   • Cache Level: Bypass
   • Disable Performance (optional)
2. For Login Page: *example.com/wp-login.php*
   • Cache Level: Bypass

This ensures Cloudflare doesn’t try to cache your admin area or login page.

---

🔧 Step 4: Cloudflare Cache Settings

• Caching → Configuration:
  • Caching Level: Standard
  • Browser Cache TTL: Respect Existing Headers
  • Always Online: optional
• Speed → Optimization:
  • Rocket Loader → OFF (can break JS-heavy plugins)
  • Auto Minify → OFF if you already let LiteSpeed Cache handle minify. (Choose one system, not both.)

---

🚀 Summary

• LSCWP does smart page caching.
• Cloudflare delivers global CDN + security.
• Cloudflare API token lets LSCWP clear Cloudflare cache automatically.
• Page rules stop Cloudflare from messing with admin or login.

---

Here’s a tested LiteSpeed Cache (LSCWP) setup that works best with Cloudflare.

I’ll break it down by plugin sections.

---

🔧 LiteSpeed Cache Plugin Settings (Cloudflare setup)

1. General

• Domain Key: Request & activate (needed for QUIC.cloud services if you want Image Optimization, CSS).
• Server IP: Fill it in (your hosting IP). Helps QUIC.cloud talk to your server.
• Guest Mode / Guest Optimization: Leave ON (improves first-time visits).

---

2. Cache

• Enable Cache: ✅ ON
• Cache Logged-in Users: ❌ OFF (unless membership site / forum).
• Cache Commenters: ❌ OFF (can confuse users after posting).
• Cache REST API: ✅ ON (faster WP API, Gutenberg).
• Cache Login Page: ❌ OFF.
• Cache Mobile: ✅ ON (use “Adaptive” if theme serves different mobile content).
• Cache TTL (Time To Live):
  • Default Public Cache TTL: 604800 (7 days)
  • Front Page TTL: 604800 (7 days)
  • Feeds TTL: 0 (disable caching feeds to avoid issues).

---

3. Purge

• Auto Purge Rules for Publish/Update: ✅ (Front Page, Home, Post, Categories, Tags).
• Serve Stale: ✅ ON (serves stale content while fetching new).

---

4. Excludes

• Add:
  • /wp-admin/*
  • /wp-login.php
    (Matches your Cloudflare bypass rules, so both layers skip admin).

---

5. Optimize

• CSS Minify / Combine: ✅ ON
• JS Minify: ✅ ON
• JS Combine: ❌ OFF (can break sites, test carefully).
• Load CSS Asynchronously: ✅ ON (with Critical CSS from QUIC.cloud).
• Generate Critical CSS: ✅ ON (needs Domain Key).
• HTML Minify: ✅ ON
• Remove Query Strings: ✅ ON
• Load JS Deferred: ✅ ON (except for jQuery if needed).

👉 Turn OFF Cloudflare’s Auto Minify to avoid double-processing.

---

6. Media

• Lazy Load Images: ✅ ON
• Lazy Load Iframes: ✅ ON (good for YouTube embeds).
• Generate WebP Versions: ✅ ON (needs QUIC.cloud API).
• Image WebP Replacement: ✅ ON
• Image Optimization: Use QUIC.cloud (background processing).

---

7. CDN

• Cloudflare API: ✅ ON (with your API token).
• QUIC.cloud CDN: ❌ OFF (since Cloudflare is your CDN).

---

8. Advanced

• Instant Click: optional (preloads links on hover).
• Heartbeat Control: ✅ Reduce activity (saves server resources).
• Browser Cache: ✅ ON

---

🔧 Cloudflare Matching Settings

• Minify: OFF (let LSCWP handle).
• Rocket Loader: OFF.
• Page Rules: Bypass for /wp-admin/* and /wp-login.php*.
• Cache TTL: “Respect Existing Headers”.

---

🚀 Result

• LiteSpeed handles smart WordPress page caching + optimization.
• QUIC.cloud (optional) handles image optimization & critical CSS only.
• Cloudflare handles global CDN, SSL, security, DDoS.
• No duplicate caching, no broken pages.
