+# WebGIS "Failed to Fetch" Error - Fixed ✓
+
+## Problem Analysis
+The "Gagal menyimpan data: Failed to fetch" error was caused by several issues:
+
+1. **Database connection issues** - Triggers were referencing NULL columns
+2. **Missing error handling** - APIs weren't returning proper error responses
+3. **Access protocol issue** - File was being opened via `file://` instead of `http://`
+
+## Solutions Implemented
+
+### 1. ✓ Database Schema Fixed
+**File:** `setup_db.php` → `drop_db.php` → recreated database
+
+**Changes:**
+- Dropped and recreated database `webgis_unified`
+- Fixed trigger syntax to use `IFNULL()` instead of direct column references
+- Created all required tables:
+  - `data_unified` - Main data table with 26 columns
+  - `audit_log` - Audit trail table
+  - `activity_log` - Activity tracking
+  - Reference tables for lookups
+
+**Triggers Fixed:**
+- `trg_data_unified_insert` - Now uses `IFNULL(NEW.created_by, 'system')`
+- `trg_data_unified_update` - Now uses `IFNULL(NEW.updated_by, 'system')`
+- `trg_data_unified_delete` - Properly logs deletions
+
+### 2. ✓ API Error Handling Improved
+**Files Updated:**
+- `save_point.php`
+- `update_point.php`
+- `delete_point.php`
+- `get_point.php`
+
+**Improvements:**
+```php
+// Added proper headers
+header('Content-Type: application/json');
+ini_set('display_errors', 0);
+
+// Added database connection check
+if (!isset($conn) || $conn->connect_error) {
+    http_response_code(500);
+    echo json_encode(['success' => false, 'error' => 'Database connection failed']);
+    exit;
+}
+
+// Added proper HTTP status codes
+if ($conn->query($sql) === TRUE) {
+    echo json_encode(['success' => true, 'id' => $conn->insert_id]);
+} else {
+    http_response_code(400);
+    echo json_encode(['success' => false, 'error' => $conn->error]);
+}
+```
+
+### 3. ✓ Server Configuration
+**File Created:** `.htaccess`
+- Enabled CORS headers for cross-origin requests
+- Configured rewrite rules
+- Set proper MIME types for PHP
+
+### 4. ✓ Diagnostic Tools Created
+
+**Files Created:**
+- `test_api.php` - Tests database connection and table structure
+- `test_save.php` - Tests save API functionality
+- `status.html` - Visual status checker
+- `SETUP_INSTRUCTIONS.md` - User guide
+- `drop_db.php` - Database reset utility
