Hmmm… this error from class-bbp-converter-base.php seems never to be shown:

// Connection failed
if ( ! $this->opdb->db_connect( false ) ) {
$error = new WP_Error( ‘bbp_converter_db_connection_failed’, esc_html__( ‘Database connection failed.’, ‘bbpress’ ) );
wp_send_json_error( $error );
}

You can leave all the database fields blank or enter rubbish and it still says:

Stopped

Starting Import…

Ready to go.

Which leads me to wonder, what other informational/error messages are not shown.
