From a newbie on Backdrop CMS using the following setup:

  • Windows 10 Home
  • Backdrop v1.21.4
  • XAMPP 
  • Apache 2.4.53
  • PHP 8.1.5
  • MySQL/MariaDB 10.4.24

I have changed the mysql root password and also tried other changes but error persisted:

  • specified 'localhost' on Database host
  • specify/changed root:password in the settings.php
  • reverted to previous backdrop versions back to v1.21.1

Though I have some experience installing Drupal 6/7 sites, I am not sure how to fix this error.  Appreciate any help for a Backdrop newbie.  thanks.




thanks!  Creating a blank db first fixed the problem.
