When I connected on my WP admin dashboard, it was displaying in a simple HTML page (no CSS loaded). I found a great solution on the wordpress forum.
Simply add the following line in the wp-config.php file before the first require_once function call:
 define(‘CONCATENATE_SCRIPTS’, false);
Hope this will fix your problem.
