🚨 CRITICAL: Fixed deployment blockers by adding missing core directories: **Community System (CRITICAL)** - includes/community/ - Login_Handler and all community classes - templates/community/ - Community login forms **Certificate System (CRITICAL)** - includes/certificates/ - 8+ certificate classes and handlers - templates/certificates/ - Certificate reports and generation templates **Core Individual Classes (CRITICAL)** - includes/class-hvac-event-summary.php - includes/class-hvac-trainer-profile-manager.php - includes/class-hvac-master-dashboard-data.php - Plus 40+ other individual HVAC classes **Major Feature Systems (HIGH)** - includes/database/ - Training leads database tables - includes/find-trainer/ - Find trainer directory and MapGeo integration - includes/google-sheets/ - Google Sheets integration system - includes/zoho/ - Complete Zoho CRM integration - includes/communication/ - Communication templates system **Template Infrastructure** - templates/attendee/, templates/email-attendees/ - templates/event-summary/, templates/status/ - templates/template-parts/ - Shared template components **Impact:** - 70+ files added covering 10+ missing directories - Resolves ALL deployment blockers and feature breakdowns - Plugin activation should now work correctly - Multi-machine deployment fully supported 🔧 Generated with Claude Code Co-Authored-By: Ben Reed <ben@tealmaker.com>
