🔍 Diagnosing Upload Issue
=========================

1️⃣ Checking if files are updated on server...

Checking api.php...
❌ api.php - NOT updated on server
   Current methods: Not found
   Expected methods: GET, POST, OPTIONS
   Current headers: Not found
   Expected headers: X-Device-ID, X-Timestamp, X-Auth-Token, X-Data-Type
   OPTIONS support: ❌ Not working (HTTP 405)
   OPTIONS response: {"success":false,"message":"Method not allowed"}

Checking upload.php...
❌ upload.php - NOT updated on server
   Current methods: Not found
   Expected methods: POST, OPTIONS
   Current headers: Not found
   Expected headers: X-Device-ID, X-Timestamp, X-Auth-Token, X-Data-Type
   OPTIONS support: ✅ Working

2️⃣ Possible Issues:
==================
1. Files not uploaded to correct directory
2. Server caching (try clearing cache)
3. File permissions issue
4. Files uploaded to wrong location
5. Server not reading updated files

3️⃣ Troubleshooting Steps:
========================
1. Verify upload location: Make sure you're uploading to /php/ directory
2. Check file permissions: Files should be 644 or 755
3. Clear server cache if applicable
4. Try uploading with different filename first (e.g., api_new.php)
5. Check if files are actually on server via FTP/cPanel

4️⃣ Test with different filename:
===============================
Try uploading api.php as api_test.php first to verify upload works:
curl "https://mobiletr.upastithi.in/php/api_test.php"

5️⃣ Current Server Status:
========================
The server is definitely running OLD versions of the files.
This means either:
- Files weren't uploaded
- Files uploaded to wrong location
- Server caching issue
- File permission issue

🔧 Next Steps:
=============
1. Double-check upload location
2. Try uploading with different filename
3. Check file permissions
4. Clear any server cache
5. Verify files are actually on server
