🔍 PRODUCTION DEBUG ANALYSIS
============================

✅ Created production debug endpoint
📁 Location: api/debug-production.php

🔧 DEBUGGING STEPS:
===================

1. DEPLOY DEBUG ENDPOINT:
   git add api/debug-production.php
   git commit -m "Add production debug endpoint"
   git push origin main
   # Then on production: git pull origin main

2. TEST DEBUG ENDPOINT:
   https://ai.proviska.com/api/debug-production.php

3. COMPARE WORKING VS FAILING FILES:
   Working: admin-activity.php (200 OK)
   Failing: admin-payments.php (500 error)
   Find the difference!

4. CHECK PRODUCTION ERROR LOGS:
   /var/log/apache2/error.log
   /var/log/php/error.log

✅ Created: api/test-simple.php
✅ Created: api/test-json.php
✅ Created: api/test-cors.php

🎯 INVESTIGATION HYPOTHESIS:
============================

LIKELY CAUSES:
1. ConfigLoader.php missing dependencies on production
2. Database connection failing in specific endpoints
3. File permissions or ownership issues
4. PHP version differences
5. Missing PHP extensions

NEXT STEPS:
1. Deploy debug endpoints with git
2. Access https://ai.proviska.com/api/debug-production.php
3. Compare error messages with local environment
4. Identify the specific failure point

💡 This will pinpoint exactly what's failing on production!
