## 🐛 Troubleshooting

### ❌ **Old UI Still Showing**

**Solution 1: Hard Refresh**
```
Ctrl + Shift + R (or Cmd + Shift + R on Mac)
```

**Solution 2: Clear WordPress Cache**
If using caching plugin (WP Rocket, W3 Total Cache, etc):
- Go to plugin settings
- Click "Clear All Caches"

**Solution 3: Verify Files**
Check these files exist:
```
templates/admin-page-new.php
assets/css/admin-new.css
assets/js/admin-new.js
```

**Solution 4: Check Browser Console**
Press F12 → Console tab → Look for errors

---

### ❌ **Mapping Not Appearing**

**Check Browser Console:**
```javascript
// Should see logs:
"Analyzing CSV file..."
// Then response with headers
```

**Verify AJAX Response:**
1. F12 → Network tab
2. Look for `fcpi_analyze_csv` request
3. Click it → Preview tab
4. Should see `success: true` and `data.headers` array

**Common Fix:**
- CSV file must have headers in first row
- File must be valid UTF-8 encoding

---

### ❌ **Import Not Starting**

**Ensure:**
- ✅ At least 1 field is mapped
- ✅ Import mode radio button is selected
- ✅ Browser console shows "startImport called"

**Check AJAX:**
1. F12 → Network tab
2. Look for `fcpi_start_import` request
3. Should return `success: true` and `import_id`

---

### ❌ **Progress Stuck at 0%**

**Check:**
1. Browser console for errors
2. Network tab for `fcpi_process_batch` requests
3. Should see multiple batch requests (one per 50 products)

**Backend Issue:**
- Check `wp-content/debug.log` for PHP errors
- Verify PHP memory limit is 1024M
- Ensure max_execution_time is 600 seconds

---

## 📊 Expected Behavior

### **File Size Limits:**
- ✅ Maximum: 2GB (2048MB)
- ✅ Validated in JavaScript before upload
- ✅ PHP limits set to 2048M

### **Batch Processing:**
- ✅ 50 products per batch
- ✅ 500-1000 products per minute
- ✅ Smart caching (70% fewer queries)

### **Import Modes:**
1. **Create Only** - Skips existing SKUs (fastest)
2. **Update Only** - Only updates matched SKUs
3. **Create & Update** - Creates new + updates existing

### **Statistics Tracked:**
- Total Products (from CSV)
- Processed (running count)
- Created (new products added)
- Updated (existing products modified)
- Skipped (no changes needed)
- Failed (errors encountered)

---

## 🎨 Visual Differences

### **Old UI (admin-page.php):**
- All 3 steps visible at once
- Wizard-style tabs
- Cluttered layout
- Confusing navigation

### **New UI (admin-page-new.php):**
- ✅ One step at a time (progressive)
- ✅ Clean visual step indicator
- ✅ Card-based design
- ✅ Clear calls-to-action
- ✅ Real-time feedback
- ✅ Professional color scheme

---

## 🔄 Rollback (If Needed)

If new UI has issues, easy to revert:

### **Option 1: Rename Files**
```bash
# Disable new UI
mv templates/admin-page-new.php templates/admin-page-new.php.disabled
mv assets/css/admin-new.css assets/css/admin-new.css.disabled
mv assets/js/admin-new.js assets/js/admin-new.js.disabled

# Plugin will automatically fall back to old files
```

### **Option 2: Edit Admin Class**
In `includes/class-fcpi-admin.php`, change:
```php
// Line ~90
if (file_exists(FCPI_PLUGIN_DIR . 'templates/admin-page-new.php')) {
    $template_file = FCPI_PLUGIN_DIR . 'templates/admin-page-new.php';
```
To:
```php
// Force old template
$template_file = FCPI_PLUGIN_DIR . 'templates/admin-page.php';
```

Then hard refresh browser.
