  25. Test with Sample Files: Use simple PHP files to test if PHP is working properly.
  26. Check for Blocked Ports: Ensure no software or system policies are blocking XAMPP’s ports.
  27. Temporary Folder Permissions: Ensure that PHP’s temporary folder (upload_tmp_dir in php.ini) has appropriate permissions.
  28. Check Environment Variables: Verify that environment variables required by XAMPP are correctly set.
  29. Check MySQL Data Directory: Ensure that MySQL’s data directory ([XAMPP installation directory]/mysql/data) is accessible and writable.
  30. Check for Conflicting Services: Investigate if other services or applications are conflicting with XAMPP.
  31. Check PHP Error Reporting: Set PHP’s error_reporting to E_ALL in php.ini to display all errors.
