I am new to Backdrop and I get a problem while installing.
I create the Database, key in the parameters : database name, database user and password ... and I get a weird message :
Error: Call to undefined method DatabaseConnection_mysql::exec() in DatabaseConnection_mysql->createDatabase() (line 217 of /var/www/consult/core/includes/database/mysql/database.inc).
I am trying to install on a Debian Bookworm with MariaDB 10.6 and PHP 8.1.7, the Backdrop version is 1.23.
All required PHP extension are installed (the first screen was OK).
