Since the new update came out (WpForo 2), logged in users, except the admin, are presented with a really annoying banner on top of my website showing this error message: "Notice: Trying to get property 'roles' of non-object in /var/www/vhosts/mydomain.com/httpdocs/wp-content/plugins/wpforo/includes/hooks.php on line 22"

I already tried many things, I was able to temporarily fix it by changing this lines of code (22-27) in the hooks.php file. I copied this code from a really old post that I found in your support forum. But as I said this just temporary, every new update I need to manually change the code. Is there a way you can help me?

ORIGINAL PIECE OF CODE:

add_action( 'show_admin_bar', function( $show_admin_bar ) {
	if( ! is_super_admin() && is_user_logged_in() && ! array_intersect( [ 'editor', 'administrator', 'author', ], (array) WPF()->wp_current_user->roles ) ) {
		$show_admin_bar = (bool) array_intersect( WPF()->current_user_groupids, wpforo_setting( 'general', 'admin_bar' ) );
	}
	return $show_admin_bar;
});



HOW I CHANGED IT: 

function my_admin_bar_control_function() {
    if (current_user_can('administrator') || current_user_can('editor') || current_user_can('author') ) {
        show_admin_bar(true);
    } else {
        show_admin_bar(false);
    }
}
add_action('init', 'my_admin_bar_control_function', 20);
