[Waiting for user feedback] the other domain changes every day automatically

Here’s a structured approach to help you identify the root cause:

- Review WordPress Scheduled Tasks (Cron Jobs)
1. Install the WP Crontrol plugin.
2. Navigate to Tools → Cron Events.
3. Look for scheduled tasks related to WPML, domain switching, or plugins that modify site settings.
4. Disable suspicious cron jobs and monitor if the issue persists.

- Check for Theme or Plugin Conflicts
1. Switch to a default WordPress theme (e.g., Twenty Twenty-Three).
2. Deactivate all plugins except WPML.
3. If the issue disappears, reactivate plugins one by one to identify the conflict.

- Audit User and Admin Activity
1. Install WP Activity Log to track changes.
2. Check if admin users, plugins, or external services modify WPML settings overnight.

- Check Database for Forced Changes
1. Use phpMyAdmin or WP CLI to inspect the database.
2. Run the following SQL query:

  
     SELECT * FROM wp_options WHERE option_name LIKE '%wpml%';  
     

3. Look for values referencing europeartfair.eu and identify any anomalies.

- Look for External Scripts or API Calls
1. Check if third-party services (automated deployments, synchronization scripts) override settings.
2. If hosted on managed WordPress hosting, ask the provider if they enforce automatic changes.

- Enable Debug Logging
1. Enable WordPress Debug Mode by adding this to

wp-config.php

:

  
     define('WP_DEBUG', true);  
     define('WP_DEBUG_LOG', true);  
     define('WP_DEBUG_DISPLAY', false);   
     

2. After 24 hours, check

wp-content/debug.log

for errors or changes related to WPML.
