Wordpress问题创建菜单选项

Question

I have created a Custom Setting API for web developing for a client. I was just creating first menu option on the WP dashboard.

But when I send file I get this error message saying --> :call_user_func_array() expects parameter 1 to be a valid callback, function ' allb_admin_page' not found or invalid function name in

function allb_admin_page() {

  add_menu_page( ' ALLB Theme Options', 'ALLB', 'manage_options', 'a-legacy-left-behind', 'allb_theme_create_page', 110);

}

add_action( 'admin_menu', ' allb_admin_page' );

function allb_theme_create_page() {
  // genration of our admin page
}

I was thinking this may be new update or this function that i am using might be removed from WordPress or i am doing something wrong please explain.

Can anyone help with this quick issue having on word press, please?

Thank you, Happy New Years!!!
