 - **Training Leads and Navigation Menu Restructure (2025-08-05)**: Implemented comprehensive Training Leads system for HVAC trainers with contact form submission management. Created new "Training Leads" page (/trainer/training-leads/) with HVAC_Training_Leads class (includes/class-hvac-training-leads.php) and dedicated template (templates/page-trainer-training-leads.php). Features tabular display of contact submissions with Date, Name, Email, Phone, City, State/Province, and Message columns, AJAX-powered status updates, empty state messaging, and CTA for profile sharing. Restructured trainer navigation menu: renamed "Customize" to "Profile", moved "Logout" under "Profile" submenu, changed "Personal Profile" to "Trainer Profile", added "Training Leads" under Profile section. Updated help menu to display only question mark icon (no text) positioned to far right using CSS flexbox (margin-left: auto, order: 999). Enhanced documentation page with complete WordPress integration, proper navigation/breadcrumbs, and updated content reflecting current platform features including Training Leads system. All components deployed to staging with comprehensive E2E test coverage verification. Navigation changes improve UX by grouping related features under logical sections and providing quick access to new lead management functionality.
 - **Joe Medosch Account Updates (2025-08-05)**: Updated user joe@upskillhvac.com (ID: 20) display name from "Joe UpskillHVAC" to "Joe Medosch". Assigned Joe as author of key organizational assets: measureQuick headquarters venue (ID: 4869), both measureQuick organizer entries (IDs: 5429, 1667), and Upskill HVAC organizer (ID: 1647). All changes verified on staging server. Joe now properly credited in system as the lead contact for primary organizational entities, ensuring accurate attribution for training events and venue management. Updates maintain data integrity while reflecting correct organizational leadership structure.
 - **Registration Form Field Updates (2025-08-08)**: Successfully optimized three registration form fields per user requirements. Business Type changed from radio buttons to dropdown with 11 specific options (Association, Consultant, Service Company, Distributor or Supplier, Sales Representative, Educational Institution, Training Organization, Equipment Manufacturer, Other Manufacturer, Government, Other). Training Audience reduced to exactly 4 multi-select checkboxes ("Anyone (open to the public)", "Industry professionals", "Internal staff in my company", "Registered students/members of my org/institution"). Organization Headquarters changed from text inputs to dynamic country/state dropdowns with automatic state/province loading for US/Canada and text input fallback for other countries. All changes tested on staging and ready for production. CRITICAL: Monitoring infrastructure permanently disabled due to PHP segmentation faults - see warning section above.
+- **Safari Browser Compatibility Resolution (2025-08-08)**: ✅ **RESOLVED** - Critical Safari browser hanging issues completely resolved through comprehensive resource loading optimization system. Root cause identified as 35+ separate CSS file enqueue calls creating a resource loading cascade that overwhelmed Safari's rendering engine. Investigation revealed JavaScript syntax error in MapGeo integration and excessive component initialization cascade. Solution: Deployed Safari-specific resource loading bypass that detects Safari browsers and loads only 1 consolidated CSS file instead of 35+, automatically dequeues non-critical assets, implements intelligent browser detection with HVAC_Browser_Detection class, and maintains full functionality while preventing browser hangs. Additional fixes: removed CSS @import statements causing render blocking, optimized database queries in find-trainer template, implemented lazy component loading, reduced Astra theme hook priorities from 999 to 50, fixed JavaScript syntax error (dangling }) in MapGeo integration. Testing verified with Playwright WebKit engine - page loads successfully with complete functionality including interactive map, trainer cards, and navigation. Resource optimization reduced CSS files from 35+ to 3 core files. Production verification confirmed: **"THE PAGE FINALLY LOADS IN SAFARI!!!!!!!"** - User confirmation of successful resolution. Complete technical documentation in docs/SAFARI-COMPATIBILITY-INVESTIGATION.md. Status: Production-ready and user-verified working.
 - **Registration Form Production Deployment and Verification (2025-08-08)**: Successfully deployed updated registration form to production environment using `scripts/deploy.sh production`. Comprehensive Playwright E2E tests executed against production site (https://upskillhvac.com/trainer/registration/) with 100% pass rate. Test verification confirmed: all 40+ form fields functional with proper Business Type dropdown (11 options), Training Audience multi-select checkboxes (4 options), dynamic Organization Headquarters country/state dropdowns with automatic US/Canada state loading, file upload functionality for profile images and organization logos, complete form submission workflow, user registration with redirect to /registration-pending/. Database verification completed on production server: user account created (ID: 65), all user meta fields stored correctly (business_name, business_email, training_audience serialized array, first_name, last_name, application_details, business_type), organizer post created (ID: 6020 - "Test HVAC Training Company 1754663473108"), venue post created (ID: 6022 - "Test Training Center Dallas 1754663473108"). Registration system fully operational in production with complete end-to-end functionality verified through automated testing and manual database inspection. Test email: test.registration.1754663473108@example.com used for verification.
