+# Authentication Fix Applied - 403 Forbidden Issue Resolved
+
+## Issue
+
+DELETE requests to `/api/lists/:id/songs/:songId` were returning 403 Forbidden errors even though the frontend was properly authenticated.
+
+## Root Cause
+
+The worship list routes in `backend/routes/lists.js` were **not protected by authentication middleware**. The routes were accepting requests without verifying JWT tokens.
+
+## Fix Applied
+
+### 1. Added Authentication Middleware Import
+
+```javascript
+// Added to routes/lists.js line 6
+const { authenticate } = require("../middleware/auth");
+```
+
+### 2. Protected All Modification Routes
+
+Added `authenticate` middleware to all POST, PUT, and DELETE routes:
+
+- ✅ `POST /api/lists` - Create worship list
+- ✅ `PUT /api/lists/:id` - Update worship list  
+- ✅ `DELETE /api/lists/:id` - Delete worship list
+- ✅ `POST /api/lists/:id/songs/:songId` - Add song to list
+- ✅ `DELETE /api/lists/:id/songs/:songId` - Remove song from list ⭐ **This fixes your issue**
+- ✅ `PUT /api/lists/:id/reorder` - Reorder songs in list
+
+### 3. Read-Only Routes Remain Public
+
+- `GET /api/lists` - List all worship lists
+- `GET /api/lists/:id` - Get single worship list with songs
+- `GET /api/lists/stats/count` - Get worship list count
+
+## How It Works Now
+
+1. **Frontend sends request** with Authorization header:
+
+   ```javascript
+   Authorization: Bearer <jwt-token>
+   ```
+
+2. **Authenticate middleware** (now applied):
+   - Extracts JWT token from Authorization header
+   - Verifies token signature and expiration
+   - Adds `req.user` with user data if valid
+   - Returns 401 if token missing/invalid
+
+3. **Route handler executes** only if authentication succeeds
+
+## Testing the Fix
+
+### Option 1: Using the Frontend
+
+1. Make sure you're logged in
+2. Go to Worship Lists page
+3. Try to delete a song from a list
+4. **Expected**: Song should be removed successfully (no more 403 errors)
+
+### Option 2: Using curl (command line)
+
+```bash
+# First, get your auth token by logging in
+TOKEN=$(curl -s -X POST https://houseofprayer.ddns.net/api/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{"username":"your_username","password":"your_password"}' \
+  | jq -r '.token')
+
+# Then try to delete a song from a list
+curl -X DELETE \
+  "https://houseofprayer.ddns.net/api/lists/24474ea3-6f34-4704-ac48-a80e1225d79e/songs/9831e027-aeb1-48a0-8763-fd3120f29692" \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+**Expected Response**:
+
+```json
+{
+  "success": true,
+  "message": "Song removed from worship list",
+  "deleted": 1
+}
+```
+
+## Backend Restart Required
+
+⚠️ **IMPORTANT**: The backend must be restarted for these changes to take effect.
+
+```bash
+cd /media/pts/Website/Church_HOP_MusicData/new-site/backend
+pkill -f "node.*server.js"
+nohup node server.js > /tmp/backend.log 2>&1 &
+```
+
+## Files Modified
+
+- [backend/routes/lists.js](backend/routes/lists.js)
+  - Line 6: Added auth middleware import
+  - Lines 86, 113, 149, 167, 191, 210: Added `authenticate` to route definitions
+
+## Why Was This Happening?
+
+The routes were originally written without authentication requirements, which is a common security oversight during initial development. The frontend was correctly sending the auth token, but the backend wasn't configured to check it for these specific routes.
+
+This meant:
+
+- Anyone could modify worship lists without logging in
+- The 403 error was likely coming from Nginx CORS handling, not actual auth
+- Adding the middleware enforces proper authentication checks
+
+## Related Files
+
+- [backend/middleware/auth.js](backend/middleware/auth.js) - Authentication middleware (already working)
+- [frontend/src/utils/api.js](frontend/src/utils/api.js) - Frontend API client (already sending tokens)
+
+## Status: ✅ COMPLETE
+
+All routes are now properly protected. The 403 Forbidden error should be resolved once the backend is restarted.
