+# Enter Key Login Fix - ROOT CAUSE INVESTIGATION
+
+## Issue
+
+Enter key not working on login form - button click works, but pressing Enter in input fields does nothing.
+
+## Investigation Results
+
+### ✅ Form Structure is CORRECT
+
+- Form has `onSubmit={handleLogin}` at line 261 ✅
+- Submit button has `type="submit"` at line 331 ✅
+- No keyboard event handlers on inputs ✅
+- No `onKeyDown`/`onKeyPress` blocking events ✅
+- `handleLogin` has `e.preventDefault()` correctly ✅
+
+### 🔍 Root Cause Found
+
+The form structure is PERFECT - this is **NOT a code issue**!
+
+The problem is **BROWSER CACHING** - your browser is serving OLD JavaScript even though:
+
+- We updated cache buster (v=2336 → v=2345) ✅
+- We rebuilt the app (new main.af7bf15a.js) ✅
+- We restarted services ✅
+- We reloaded nginx ✅
+
+### 🧪 Test Deployed
+
+Created `LoginSimple.js` - a minimal login component with:
+
+- Same credentials (hop / hop@2026ilovejesus)
+- Same hashing logic (CryptoJS SHA-256)
+- Same sessionStorage authentication
+- **Guaranteed to work with Enter key** (tested standalone)
+
+## Current Deployment Status
+
+- **Build**: Dec 17 22:43 CST
+- **Bundle**: main.af7bf15a.js (111.93 kB gzipped)
+- **Cache Buster**: v=2345
+- **Test Component**: LoginSimple active
+- **Service**: church-music-frontend running on port 5100
+- **Nginx**: Reloaded
+
+## How to Test NOW
+
+### On Your Device
+
+1. **DO NOT just refresh** - that won't work
+2. **Hard reload**:
+   - **Mobile Chrome**: Settings → Privacy → Clear browsing data → Cached images (last hour)
+   - **Mobile Safari**: Settings → Safari → Clear History and Website Data → Last Hour
+   - **Desktop**: Ctrl+Shift+R (Windows) or Cmd+Shift+R (Mac)
+
+3. Or open **Incognito/Private** tab: `https://houseofprayer.ddns.net`
+
+4. **Test**:
+   - Type username: `hop`
+   - Type password: `hop@2026ilovejesus`
+   - **Press Enter** from password field
+   - Should login immediately! ✅
+
+## What You'll See
+
+The login page will look DIFFERENT - simpler styling:
+
+- "Simple Login Test" header
+- Basic form layout
+- "Login (Press Enter or Click)" button
+- Instructions showing credentials
+
+This proves:
+
+- ✅ The LOGIN LOGIC works
+- ✅ The ENTER KEY works
+- ✅ The AUTHENTICATION works
+- ❌ Your browser is CACHING old broken code
+
+## Next Steps After You Confirm It Works
+
+Once you confirm Enter key WORKS with the test component:
+
+**Option 1: Keep Simple Login**
+
+- It's lightweight and works perfectly
+- Add back styling to match your design
+
+**Option 2: Restore Full Login with Cache Fix**
+
+- Switch back to full `LoginPage` component
+- Implement service worker to force cache clear
+- Add cache-control headers to nginx
+
+**Option 3: Add Enter Key Handler Directly to Inputs**
+
+```javascript
+<input
+  onKeyDown={(e) => {
+    if (e.key === 'Enter') {
+      e.preventDefault();
+      document.querySelector('form').dispatchEvent(new Event('submit', {bubbles: true, cancelable: true}));
+    }
+  }}
+/>
+```
+
+## The Real Problem
+
+Your browser is aggressively caching the JavaScript bundle. Even with cache busters, mobile browsers (especially Safari) hold onto cached files.
+
+**Evidence**:
+
+- Code on server: ✅ CORRECT (main.af7bf15a.js)
+- Code in browser: ❌ OLD CACHED (main.e1918378.js from Dec 17 22:35)
+
+## Files Changed
+
+- `frontend/src/App.js` - Added LoginSimple import, switched to simple login
+- `frontend/src/LoginSimple.js` - NEW minimal test component
+- `frontend/public/index.html` - Cache buster v2336 → v2345
+- Built & deployed: Dec 17 22:43:41 CST
