Embeddings Are Not Auto-Synced

Possible Causes

• WordPress Cron Jobs Not Running: The AI Engine relies on scheduled events (cron jobs) to update embeddings every few minutes. If these cron jobs aren't running, embeddings won't auto-sync.

• Server-Level Password Protection: If your website (including wp-cron.php) is behind a server-level password protection (like cPanel directory privacy), it can prevent cron jobs from executing.

• Plugin Conflicts: Security, caching, or optimization plugins might interfere with scheduled events.

• Misconfigured wp-config.php: Disabling WP-Cron in the configuration file stops all scheduled tasks.

How to Diagnose the Issue

1. Install WP Crontrol Plugin

• Step: Install and activate the WP Crontrol plugin.

• Purpose: This plugin lets you view and manage all cron events in WordPress.

2. Check Cron Events

• Navigate to: Tools > Cron Events in your WordPress dashboard.

• Look for:
• The mwai_5mn event (used by AI Engine for embeddings).
• Any errors or warnings next to scheduled events (e.g., HTTP 401 errors).

3. Identify Errors

• HTTP 401 Errors: Indicates unauthorized access, possibly due to password protection blocking wp-cron.php.

• No Scheduled Events: Suggests that WP-Cron might be disabled or not functioning.

Solutions

1. Remove Server-Level Password Protection

• Disable Directory Privacy:
• Log in to your hosting control panel.
• Navigate to Directory Privacy or similar.
• Remove the password protection from your website directory.

• Alternative: Use a WordPress plugin like Password Protected to restrict site access without blocking wp-cron.php.

2. Check for Plugin Conflicts

• Disable Other Plugins:
• Temporarily deactivate security, caching, or optimization plugins.
• Check if embeddings start auto-syncing.

• Reactivate Plugins One by One:
• Identify if a specific plugin is causing the conflict.

3. Verify WP-Cron Is Enabled

• Check wp-config.php:
• Access your website files via FTP or a file manager.
• Open the wp-config.php file.
• Ensure there's no line that says define('DISABLE_WP_CRON', true);. If it exists, remove it or set it to false.

4. Use an External Cron Job

• Set Up a Server Cron Job:
• Schedule a cron job on your server to call wp-cron.php at regular intervals.
• This bypasses the need for visitors to trigger cron events.

Confirm the Fix

1. Edit a Post: Make a change to any post to initiate the embedding process.

2. Visit Your Website: Load any page to trigger WP-Cron (if using WP-Cron).

3. Check Embeddings:
• Go to AI Engine > Embeddings.
• Verify that the embeddings have been updated.

Additional Tips

• Regular Monitoring: Keep an eye on cron events using WP Crontrol to ensure they're running smoothly.

• Hosting Support: If issues persist, contact your hosting provider to check for server-side restrictions.

• Stay Updated: Ensure all plugins and WordPress are up-to-date to minimize compatibility issues.
