Hi Tosin,
I had a look at their reply.

It seems the assumption might be correct.

1. try registering with a new account and see if it still giving the same issue
2. If you want to update for existing users, Please use phpmyadmin and select the usermeta table. Then search for ‘_has_complete_profile’. Remove these entries and it will work.

PS:- If you are not familiar with DB update, Please feel free to share the details and I will update it for you.

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 Daniel,
May I check the site.

An admin account for testing setting and a guest account for testing deactivation will help.
