📊 VERIFICATION SUMMARY
=======================
Total endpoints: 10
Working correctly: 10
Still have issues: 0

🎉 ALL ADMIN ENDPOINTS FIXED!
=============================

✅ RESOLUTION SUMMARY:
   • Fatal getAllHeaders() errors eliminated
   • CORS headers properly configured
   • JSON output no longer corrupted
   • Admin panel should load without errors

🔄 NEXT STEPS:
   1. Refresh admin dashboard (clear browser cache)
   2. Test individual admin sections
   3. Verify all data loads properly
   4. Deploy to production if working locally

🚨 ROOT CAUSE IDENTIFIED:
   The automated CORS fix incorrectly used 'self::getAllHeaders()'
   instead of 'getAllHeaders()' causing PHP fatal errors that
   prevented proper JSON output and caused 500 status codes.
