From your pastebin:
if (!function_exists('wp_get_current_user')) {
include_once( ABSPATH . 'wp-admin/includes/pluggable.php' );
}
if ( is_super_admin() ) {
add_action( 'admin_init', 'myplugin_register');
add_action( 'admin_menu', 'myplugin_menu' );
}
There is no file at wp-admin/includes/pluggable.php
. pluggable.php
is at wp-includes/pluggable.php
, but I see no reason you should have to intentionally include that file. It load front and back end.
