  We can’t help with custom coding, nor can we help as your site isn’t running on the wordpress.com platform. – https://wordpress.com/site-profiler/http://staging.themusicrealm.com

  The $subject is, as you might expect, required. Look into what you’re calling it with, you’re probably sending it something that doesn’t exist like $array[‘does_not_exist’].

  Hello Robol1,
  
  Thanks for letting us know. The notice you’re seeing is a PHP deprecation notice. This means that the code in WordPress is using a function in a way that will no longer be supported in future PHP versions. However, this does not impact your site’s performance or functionality. Deprecation notices are primarily for developers to update their code to ensure compatibility with future PHP releases.
