MySQL 8.0.22-0ubuntu0.20.04.3 (Ubuntu) WordPress 5.6 CiviCRM 5.32.2

Attempting a fresh install of WP and CiviCRM on a clean AWS site as upgrading CiviCRM was continually failing

I get this error:

System Requirements We are not able to install the software. Please review the errors and warnings below.

Severity Section Name Details Error Database CiviCRM MySQL Trigger Database does not support creation of triggers Refresh After updating your system, refresh to test the requirements again. Environment The system settings were auto-detected. CiviCRM will be installed with:

CMS Database mysql://wpdbuser:HIDDEN@localhost/wordpress

CiviCRM Database

CiviCRM Settings File /var/www/wordpress/wp-content/uploads/civicrm/civicrm.settings.php

CiviCRM Source Code /var/www/wordpress/wp-content/plugins/civicrm/civicrm

My Wordpress database user has full privileges including TRIGGER.

mysql> SHOW GRANTS FOR 'wpdbuser'@'localhost';
| Grants for wpdbuser@localhost                                   |
| GRANT USAGE ON *.* TO `wpdbuser`@`localhost`                    |
| GRANT ALL PRIVILEGES ON `wordpress`.* TO `wpdbuser`@`localhost` |
2 rows in set (0.01 sec)

I specifically added TRIGGER

mysql> GRANT  TRIGGER ON wordpress.* TO 'wpdbuser'@'localhost';
Query OK, 0 rows affected (0.01 sec)

How can I resolve this ? Is this a CiviCRM problem or a MySQL issue?

In the MySQL CLI, run:

SET GLOBAL log_bin_trust_function_creators=1;
