Error: connect ECONNREFUSED 127.0.0.1:3306

Solution:

1. Verify MySQL running: mysql -u root -padmin -e "SELECT 1"
2. Check .env DATABASE_URL
3. Ensure port 3306 is available

Error: Failed to collect page data

Solution:

1. Run: npx prisma generate
2. Run: npx prisma db push
3. Run: npm run build again

Solution:

1. Verify seeds ran: npm run db:seed
2. Check credentials in code (admin/1234, staff/staff123)
3. Verify users in database: npm run db:studio

1. Start MySQL (if not running)
2. Create medicore database (if not exists)
3. Run setup commands:

   cd D:\Projects\MediCore\medicore-nextjs
   npm install
   npx prisma generate
   npx prisma db push
   npm run db:seed
   npm run dev

4. Open http://localhost:3000
5. Login with admin/1234
6. Explore all modules
7. Refer to README_COMPLETE.md for details
