## Recent Fixes & Updates

### Master Dashboard Navigation Overhaul (August 22, 2025) ✅
**Complete refactoring of master dashboard layout and navigation system**

- **Problems Fixed**:
  - Two-column layout issue with navigation appearing as unwanted sidebar
  - Breadcrumb method error causing PHP fatal errors
  - Hierarchical URL detection failure with `is_page()` function
  - Redundant button navigation creating duplicate UI elements
  - Content blocking from dual authentication systems

- **Solutions Implemented**:
  - Created `hvac-master-dashboard.css` to force single-column layout
  - Fixed breadcrumb method call (`render()` → `render_breadcrumbs()`)
  - Enhanced URL detection in `HVAC_Scripts_Styles::is_master_dashboard_page()`
  - Removed old button-based navigation (Google Sheets, Templates, Trainer Dashboard, Logout)
  - Integrated all functionality into organized dropdown menu structure:
    - Google Sheets → Tools dropdown
    - Communication Templates → Tools dropdown
    - Trainer Dashboard → Account dropdown
    - Logout → Account dropdown

- **Files Modified**:
  - `templates/page-master-dashboard.php` - Navigation moved inside content wrapper
  - `assets/css/hvac-master-dashboard.css` - New CSS for layout control
  - `includes/class-hvac-scripts-styles.php` - Added master dashboard detection
  - `includes/class-hvac-master-menu-system.php` - Enhanced menu structure
  - `templates/template-hvac-master-dashboard.php` - Removed button navigation

- **Known Issues**: Navigation color scheme needs aesthetic improvements

### Enhanced CSV Import System (August 4, 2025) ✅
**Comprehensive CSV import system with taxonomy integration**

- **Problem**: Trainer profiles missing critical information from CSV file - phone numbers, company websites, certification details, business classifications
- **Root Cause**: Import system using hardcoded data instead of reading actual CSV file with 19 available fields
- **Solution**: Complete CSV import system redesign with comprehensive field mapping
- **Key Features**:
  - Reads actual `CSV_Trainers_Import_1Aug2025.csv` file (43 trainer records)
  - Imports all 19 fields: contact info, professional details, certification data
  - Full taxonomy integration for business types and training audiences
  - Automatic venue/organizer creation based on CSV flags
  - Multi-value taxonomy handling (comma-separated values)
  - Comprehensive error handling and progress tracking
- **Result**: Complete trainer profiles with professional information, proper categorization, and enhanced event management capabilities

### Certificate Pages Template System (August 1, 2025) ✅
**Fixed critical template loading issue affecting certificate pages**

- **Problem**: Certificate pages (`/trainer/certificate-reports/`, `/trainer/generate-certificates/`) were bypassing WordPress template system, showing bare shortcode content without theme headers, navigation, or styling
- **Root Cause**: `load_custom_templates()` method loading content-only templates instead of proper page templates
- **Solution**: Updated template paths to use full page templates with proper WordPress integration
- **Additional Fixes**: 
  - Eliminated duplicate breadcrumbs by disabling Astra theme breadcrumbs on plugin pages
  - Restored missing navigation menu by removing problematic constant checks
- **Result**: Certificate pages now display with complete theme integration, proper headers/footers, navigation, and consistent styling
