I greped a 3.6 install and got this: ./wp-login.php:321:function register_new_user( $user_login, $user_email ) { ./wp-login.php:550: $errors = register_new_user($user_login, $user_email); Notice the function definition is in wp-login.php.

You are using add_settings_field wrong: the function sl_wp_create_user is being passed as $args (and you probably don’t need any args), and it should be the sanitize callback for register_settings. Make the input like: function sl_render_users_input() { echo ‘<input id=”num_users[value]” name=”num_users[value]” type=”input” value=”” />’; } And the sanitize function: function sl_wp_create_user( $input ) { if( isset( … Read more
