 - **Complete End-to-End Testing (2025-07-15)**: Comprehensive testing suite implemented and verified on staging server. Event creation workflow fully functional with 6/6 essential form elements accessible, form submission working without errors, and data persistence verified. Certificate generation workflow 100% operational with 16 events available, 3 active download links returning HTTP 200 status, and complete event-certificate integration. All tests pass including authentication (100%), certificate interface (100%), event creation (form accessibility and submission), and data persistence across sessions. System production-ready with 85-90% test coverage achieved.
 - **Master Dashboard User Role Fix (2025-07-23)**: Resolved critical issue where 11 HVAC trainers with legacy `event_trainer` roles were not appearing in the master dashboard. Root cause: master dashboard code only queried for `hvac_trainer` and `hvac_master_trainer` roles, missing users with the legacy `event_trainer` role from previous development. Solution: Migrated all 11 users from `event_trainer` to `hvac_trainer` role, increasing visible trainers from 4 to 15 in master dashboard. All legacy role artifacts cleaned up. Master dashboard now shows complete trainer statistics (15 total trainers, 16 total events) and all trainer data is properly accessible to master trainer users.
 - **Admin Bar and Zoho CRM Enhanced Fixes (2025-07-23)**: Implemented robust fixes for admin bar hiding and Zoho CRM integration issues. Admin bar: Added multiple hook points (after_setup_theme, init, wp), centralized hiding function with global constant, PHP_INT_MAX priority filters, and user meta updates. Zoho CRM: Enhanced production detection with URL parsing, aggressive OAuth rewrite rule flushing with cache clearing, and improved refresh token handling. Both fixes include extensive debug logging. Deployed to staging.
+- **Event Manage Page Toolbar (2025-07-23)**: Added navigation toolbar to /trainer/event/manage/ page to match other trainer pages. Includes Dashboard, Certificate Reports, and Generate Certificates buttons with consistent styling and responsive design. Uses hierarchical URL structure.
