# 🎉 TechZone E-Commerce Platform - Complete & Fixed

## 📋 Issue Resolution Summary

### Problem Identified

The admin dashboard was displaying a **"Failed to load dashboard data"** error message.

### Root Cause

The `/api/admin/dashboard` endpoint in `backend/server.py` had **duplicate return statements** (lines 769 and 785), causing the function to exit early with the first return statement while the second (complete) return statement was never executed.

### Solution Applied

✅ **Removed the duplicate return statement** - keeping only the single, correct return with complete data structure.

- `backend/server.py` - Fixed `get_admin_dashboard()` function (line 785)
