Remove Admin Bar for all Users

Hi Guys,

I seem to be having a problem with removing the Admin Bar that runs across the front end site.

I am wanting to remove this and have tried almost every way I have read online.

Here are the steps I have done already:

1)

// Only display to administrators
add_action('after_setup_theme', 'remove_admin_bar');

function remove_admin_bar() {
if (!current_user_can('administrator') && !is_admin()) {
  show_admin_bar(false);
}
}

2)

// Disable for specific role (in this case, 'subscriber')
function remove_admin_bar() {
$user = wp_get_current_user();

if (in_array(‘subscriber’, $user->roles)) {
show_admin_bar(false);
}
}

3) add_filter('show_admin_bar', '__return_false');

4) Installed various plugins such as: Disable WP Admin Bar Removal – Remove Admin Bar – Global Hide Admin Bar and etc.

I cannot seem to get this bar removed. Has something changed in the code?

There is an option to Hide the bar in the user profiles, I do not want to do this everytime someone new joins the site as it is a magazine site.

Thanks
