# Admin Panel Fixes and Enhancements - Implementation Summary

## Critical Issues Resolved ✅

### 1. Blade Syntax Error (FIXED)
- **Issue**: Missing `@endif` directive in `resources/views/admin/users/index.blade.php`
- **Solution**: Added the missing closing directive to prevent ParseError
- **Impact**: Admin user management page now loads correctly

### 2. Setting Model Conflict (FIXED)
- **Issue**: `Setting::all()` method conflicts with Eloquent's `all($columns = [...])` signature
- **Solution**: Renamed method to `getAllSettings()` to avoid signature conflicts
- **Impact**: No more method signature conflicts, maintains backward compatibility
