| XF 2.3 Add-ons (Free) LLMO SEO Indexing AI Addon 3.1.3 Patch 1

Add-on for SEO using artificial intelligence.

LLMO SEO automatically injects structured JSON-LD metadata (Schema.org + custom "llmo" context) into XenForo threads, resources, forums, and user profiles. It improves SEO and makes forum content machine-readable for search engines and AI models. Compatible with XenForo 2.3.7+ and PHP 8.4.

What has changed compared to version 3.1.0

• Without hashes.json → no more error «N files missing» during installation.
• PHP fixes in the controller and service (correct concatenation, adding arrays, =, correct ternary operators).
• Single namespace Sylvain\LlmoproV311 to prevent conflicts with previous versions.
• Minimal, correct routes.xml file (no message «Please enter a valid value»).
• Clean setup (tables xf_llmopro_document and xf_llmopro_log).

Structure
upload/src/addons/Sylvain/LlmoproV311/

• addon.json (v3.1.1, requires XF ≥ 2.3.0+)
• Setup.php
• _data/
  • options.xml
  • phrases.xml
  • template_modifications.xml
• routes.xml → llmopro prefix
• Entity/Document.php, Entity/Log.php
• Service/Generator.php
• Util/RateLimiter.php
• Pub/Controller/Index.php, Pub/View/Json.php
• Cron/Regenerate.php, Job/WebhookPing.php
• README.txt, LISEZMOI.txt (at the root of the zip archive)

Installation (clean)

• Upload the contents of upload/to the XenForo root (on the same level as src/and admin.php).
• ACP → Supplements → Installation of LLMO Pro (Sylvain) — V3.
• ACP → Tools → Recreate Caches (Templates, Phrases, Routes).

End points

• /llmopro — manifest/info
• /llmopro/threads
• /llmopro/thread?thread_id=123
• /llmopro/search?q=...
• /llmopro/sitemap
• /llmopro/well-known

If another user is still not working

• Check the exact path: src/addons/Sylvain/LlmoproV311/ (case sensitive).
• Make sure the server does not have an upload subfolder.
• Directories 755, files 644.
• Remove all old Llmopro/LlmoproV3 to avoid accidental file merging.
• If you still need an integrity check, I can provide a server script to generate hashes.json from files that are actually present after installation.

Clean installation plan without surprises (XenForo 2.3. x) + our add-on
1) Server requirements

• PHP ≥ 8.1 (8.2/8.3 — good), MySQL ≥ 5.7/MariaDB 10.3+
• Extensions: mbstring, json, gd, curl, xml
• Access rights: 755 directories/644 files

2) XenForo installation (clean)

• Unpack XF → upload to site root.
• Run /install/ → create a database → as administrator.
• In src/config.php, make sure:
  • $config['enableAddOns'] = true;
  • $config['upgradePending'] = false;
  • $config['enableMaintenance'] = false;

ACP → Tools → Rebuild Caches (Start from Clean State).

3) Installation of the LLMO Pro add-on (fixed build).

• Use the fixed package (without hashes.json).
• Upload the contents of upload/to the XF root (at the same level as src/and admin.php).
• ACP → Supplements → Installation of LLMO Pro (Sylvain) — V3.
• ACP → Tools → Reassembling Caches (Templates, Phrases, Routes).
• If you ever need a file integrity check, we will generate hashes.json after installing it on the server (no more false «missing files»).

4) Smoke tests

• Open the branch page → in HTML code you should see <script id="llmopro-seo" type="application/ld+json">.

Public endpoints:

• /llmopro
• /llmopro/threads
• /llmopro/thread?thread_id=1 (use real id)
• /llmopro/search?q=test
• /llmopro/sitemap

5) Useful Options (ACP → Options → LLMO Pro)

• Enable/disable JSON-LD injection
• Summary length
• ETag/If-Modified-Since
• Speed limit
• Basic masking of personal data
• Web hook (optional)

6) Testing guidelines

• Test with default XF style (without overriding patterns) to identify problems. If the message «Please enter a valid value» for routes appears during reassembly:
• Temporarily rename _data/routes.xml to routes.off.xml and reassembly.
• I'll give you a small script to create a route directly in the database (more reliable) and then reassemble the caches.
