Comment (by pbiron):

 Hi @tmfhokies, welcome to Trac!

 The problem you're experiencing is because of the way you're calling
 `add_hook()`.  `add_hook()` has an optional 2nd & 3rd parameter: the 3rd
 is "The number of arguments the function accepts".  For more details, see
 [https://developer.wordpress.org/reference/functions/add_action/
 add_action()].

 If you change the call to:

 {{{
 #!php
 <?php
 add_action('wp_login', function ($user_login, $user) {
 }, 10, 2 );
 }}}

 you will find the error no longer happens.
