WordPress multisite dashboard not working..!

Open up your wp-config.php file. Turn off script concatenating by adding this line:

define('CONCATENATE_SCRIPTS', false);

Make sure you add this before:

/** Absolute path to the WordPress directory. */
if ( !defined('ABSPATH') )
        define('ABSPATH', dirname(__FILE__) . "https://wordpress.stackexchange.com/");

Hopefully this helps you save the day for your WordPress installs!
But not sure the admin pages. It will solve your dashboard issue.
