# Sinople Theme — Dogfooding Lessons
4+
5+
Learnings from deploying sinople to joshua.jewell.nexus, jonathan.jewell.nexus,
6+
and nuj-lcb.org.uk on Verpex shared hosting (LiteSpeed + cPanel, March 2026).
7+
8+
## Deployment Environment
9+
10+
| Property | Value |
11+
|----------|-------|
12+
| Web Server | LiteSpeed (native, not OLS) |
13+
| PHP | 8.2.29 via LSAPI |
14+
| OPcache | Enabled |
15+
| Redis/Memcached | Not available (shared hosting) |
16+
| APCu | Not available |
17+
| Imagick | Not available |
18+
| CDN | Cloudflare (proxied, Full Strict SSL) |
19+
20+
## Corrective (Bugs Found)
21+
22+
### C1: mu-plugin WP_DEBUG conflict (CRITICAL)
23+
**Problem:** First-run mu-plugin tried to `define('WP_DEBUG', ...)` which conflicts
24+
with wp-config.php's existing definition, causing a fatal error that blocks the
25+
WordPress installer entirely.
26+
27+
**Fix:** Never define constants in mu-plugins that wp-config.php already defines.
28+
Use `defined()` guard or simply don't touch WP_DEBUG in plugins.
29+
30+
**Action:** Add a guard to any generated mu-plugin code:
31+
```php
32+
if (!defined('WP_DEBUG')) { define('WP_DEBUG', false); }
33+
```
34+
35+
### C2: Self-signed SSL blocks Cloudflare Strict mode
36+
**Problem:** New cPanel accounts get self-signed SSL certs. Cloudflare's Full
37+
(Strict) mode rejects these, returning 526/suspended errors. AutoSSL takes
38+
~24 hours to issue Let's Encrypt certs.
39+
40+
**Fix:** Temporarily set Cloudflare SSL to "Full" (not strict) for new domains.
41+
Switch back to "Strict" after AutoSSL completes.
42+
43+
**Action:** Document this in the deployment runbook. Consider adding a Cloudflare
44+
API check to the deployment script that monitors AutoSSL status and switches
45+
SSL mode automatically.
46+
47+
### C3: cPanel package limits block subdomain creation
48+
**Problem:** Default `experien_minimal` package had MAXSUB=1 and MAXSQL=1,
49+
blocking creation of multiple subdomains/databases on the same account.
50+
51+
**Fix:** Updated package to MAXSUB=10, MAXSQL=10 via WHM API, then reapplied
52+
to the account with `changepackage`.
53+
54+
**Action:** Set higher defaults in the package from the start. Add these limits
55+
to the deployment checklist.
56+
57+
## Adaptive (Environment Differences)
58+
59+
### A1: LiteSpeed vs Apache vs nginx
60+
The theme README says "Apache/nginx + PHP-FPM" but the Verpex shared hosting
61+
runs **LiteSpeed** with LSAPI. LiteSpeed Cache plugin works natively (not via
62+
.htaccess rewrite rules as with Apache). This is actually better performance
63+
but the documentation should reflect this.
64+
65+
**Action:** Update CLAUDE.md deployment mode to mention LiteSpeed as a supported
66+
(and preferred) web server. LiteSpeed Cache plugin should be listed as a
67+
recommended plugin for LiteSpeed deployments.
68+
69+
### A2: No object cache on shared hosting
70+
Redis/Memcached are unavailable on shared hosting. LiteSpeed Cache's object
71+
cache mode falls back to file-based. This is adequate for personal sites but
72+
the documentation should note the performance difference.
73+
74+
**Action:** Add a "Hosting Requirements" section to README distinguishing
75+
"recommended" (Redis, PHP 8.3+, Imagick) from "minimum" (PHP 8.1+, OPcache).
76+
77+
### A3: PHP 8.2 vs 8.4
78+
Server runs PHP 8.2.29 (fine) but MultiPHP feature is disabled on the reseller.
79+
The theme's functions.php doesn't use any PHP 8.3+ features so this is safe,
80+
but we should note minimum PHP version explicitly.
81+
82+
**Action:** Add `Requires PHP: 8.1` to style.css theme header.
83+
84+
### A4: Cloudflare performance stack
85+
The full performance stack in production is:
86+
1. LiteSpeed Cache (page cache, CSS/JS combine, WebP, lazy load)
87+
2. Cloudflare (Brotli, minify, Rocket Loader, Early Hints, HTTP/3, aggressive caching)
88+
3. OPcache (bytecode cache)
89+
90+
This three-layer approach delivers ~106ms TTFB on a shared host. Document this
91+
as the recommended production stack.
92+
93+
## Perfective (Improvements)
94+
95+
### P1: Theme file count
96+
The deployed sinople in lcb-website has 51 PHP files. The minimal version
97+
created for jewell.nexus sites has 9 files and still looks correct. Consider
98+
which of the 42 additional files are actually needed vs. aspirational.
99+
100+
**Core files (9):** style.css, functions.php, header.php, footer.php, index.php,
101+
single.php, page.php, 404.php, sidebar.php
102+
103+
**Nice-to-have:** archive.php, search.php, comments.php, template-parts/*,
104+
inc/custom-post-types.php, inc/semantic.php, inc/indieweb.php
105+
106+
**Only needed for semantic features:** single-construct.php,
107+
single-entanglement.php, inc/taxonomies.php, WASM modules
108+
109+
**Action:** Create a "sinople-lite" variant that ships only the 9 core files
110+
plus archive.php and search.php. The full semantic/IndieWeb/WASM stack remains
111+
in sinople-full.
112+
113+
### P2: Automated deployment script
114+
The deployment process requires 6 separate cPanel API calls (create subdomain,
115+
create database, create user, grant privileges, upload WordPress, configure).
116+
This should be a single `just deploy-wordpress <domain>` recipe.
117+
118+
**Action:** Create `scripts/deploy-wordpress.sh` that automates the full flow
119+
via WHM API. Include Cloudflare DNS record creation.
120+
121+
### P3: Security hardening defaults
122+
The following settings should be baked into the theme's functions.php rather
123+
than requiring manual configuration:
124+
- Disable file editor (`DISALLOW_FILE_EDIT`)
125+
- Disable XML-RPC (unless needed)
126+
- Disable pingbacks and trackbacks
127+
- Close comments by default
128+
- Remove WordPress version from headers
129+
130+
**Action:** Add these to functions.php as opt-out (enabled by default, can be
131+
disabled via theme customizer).
132+
133+
### P4: LiteSpeed Cache optimal defaults
134+
Document the optimal LiteSpeed Cache settings as a deployable configuration:
135+
- Page cache: on
136+
- Browser cache: on
137+
- Mobile cache: on (separate)
138+
- CSS/JS minify + combine: on
139+
- Google Fonts async: on
140+
- Image lazy load: on
141+
- WebP replace: on
142+
- Crawler: on
143+
- Public TTL: 7 days
144+
- Feed TTL: 1 hour
145+
146+
**Action:** Create `config/litespeed-cache.json` with these defaults that can
147+
be imported via the LiteSpeed Cache plugin's import feature.
148+
149+
### P5: Cloudflare baseline settings
150+
Document and script the Cloudflare security + performance baseline:
151+
152+
**Security:** SSL strict, TLS 1.2 min, Always HTTPS, HSTS (1yr, subdomains),
153+
TLS 1.3 0-RTT, security level high, browser integrity check, email obfuscation,
154+
hotlink protection.
155+
156+
**Performance:** Brotli, auto minify (CSS+JS+HTML), Early Hints, HTTP/3,
157+
Rocket Loader, aggressive caching, respect origin cache headers.
158+
159+
**Action:** Create `scripts/cloudflare-baseline.sh` that applies these settings
160+
to any zone via the Cloudflare API.
161+
162+
## Performance Benchmarks (2026-03-16)
163+
164+
| Site | TTFB | Total | Size | Notes |
165+
|------|------|-------|------|-------|
166+
| joshua.jewell.nexus | 106ms | 107ms | 3.1KB | Fresh install, no content |
167+
| jonathan.jewell.nexus | 116ms | 116ms | 3.1KB | Fresh install, no content |
168+
| nuj-lcb.org.uk | 150ms | 151ms | 1.0KB | Redirect (suspended?) |
169+
170+
Benchmark conditions: curl via Cloudflare, HTTP/1.1, single request (no warm cache).
171+
LiteSpeed Cache crawler has not run yet — expect faster responses after crawl.
