如何删除插件类中的wordpress中的动作？

Question

I'm using awesome support plugin for creating a ticket system in my project , the problem I have is that support plugin will add some fields into Users Admin page which I don't want them. I searched inside plugin code and I've found the action that is used to put the fields in users page and I want to remove that action.

I tried removing its action by using this code:

remove_action('wpas_all_user_profile_fields', array( WPAS_User::get_instance() , 'profile_phone_fields'), 10)

and it is working and the fields doesn't show on users page but I'm getting a fatal error inside my debug.log which says:

 PHP Fatal error:  Uncaught Error: Class 'WPAS_User' not found in ...

the plugin class that is something like this

class WPAS_User {

  public function __construct() {
     add_action( 'wpas_all_user_profile_fields', array( $this, 'profile_phone_fields' ), 10, 1 );
 }


  public static function get_instance() {

        // If the single instance hasn't been set, set it now.
    if ( null == self::$instance ) {
            self::$instance = new self;
        }

        return self::$instance;
  }

.

}

Do you include in your php the name of the file ?

<?php include('yourfile.php') ?>
