    Hi there, I have a general WP login issue, which I hope you can help me with.

    I’m using this code snippet below, to disable WP dashboard, for other users than admins.

    Anyway, sometimes users without admin status, are able to log into their dashboard. This happens after a second login attempt with this cookie warning:

    Error: Cookies are blocked or do not understand by your browser. You must enable cookies
    to using WordPress.

    Here’s the code snippet I have added to avoid dashboard access for others than admins:

    //Disable Admin Bar for All Users Except for Administrators
add_action( 'after_setup_theme', 'remove_admin_bar' );

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

    How can this happen anyway?

    Thanks!

    Regards
    Carsten

    Hello Carsten,

    Please try the following code. If you want to hide admin bar from non administrator and do not want to give access them to dashboard.

    
// To hide admin bar to non administrator.
add_action('after_setup_theme', function(){
	if ( is_super_admin() ) {
		return;
	}

	show_admin_bar( false );

	if ( is_admin() && ! wp_doing_ajax() ) {
		wp_safe_redirect( home_url() );
		exit;
	}
});

    Please do let me know if it works or not.

    Regards
    Ravi

    Hi Ravi, thanks very much for your prompt reply and a code solution.

    Unfortunately the code breaks my site, would you please check again for a syntax error?

    Thanks!

    Hi Carsten,
    Ravi is away, so I am updating the code.

    Please use this snippet

    
// To hide admin bar to non administrator.
add_action( 'init', function () {
	if ( is_super_admin() ) {
		return;
	}

	show_admin_bar( false );

	if ( is_admin() && ! wp_doing_ajax() ) {
		wp_safe_redirect( home_url( '/' ) );
		exit;
	}
} );

    Does it work fro you?

    Hi Ravi, found this snippet which works as well:

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

    Thanks!

    Hi,
    Avoid using ‘after_setup_theme’. The current user is not set at this hook, so it should not be used.

    Hi Brajesh, thanks again, for your expert advice regarding the other code.

    I have pasted your updated code in now, and it is working perfectly!

    Thanks again, to both of you!
