Has this always happened? Or is this a new install?
Are you using subdomains or subfolders?
What’s in your .htaccess?
ETA: From your other posts:
why individual dashboard are not showing per site. all sites generate default dashboard and settings effect all. instead of being individual. multisite set up on subdirectory on wordpress 3.9.1 on shared godaddy hosting.
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', false);
define('DOMAIN_CURRENT_SITE', 'sample.com');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

its a new installation. im using subfolders. sorry for the duplicate but i was just getting frustrated. i searched the web and forums and nothing to no avail. I ended up deleting cause i was wasting time really. i dont know much about wordpress im currently starting to use this cms and with wordpress you quite on your own unless you find someone willing to help. i wanted to use multisite to avoid creating separate duplicate sites
It’s hard to get started, and I always tell people to make sure they know WORDPRESS before adding on multisite. You’re starting in the deep end of WP, and we do expect you to be familiar with the basics.
Fwiw I wrote an ebook to help people get started: https://store.halfelf.org/ebooks/wordpress-multisite-101/ (it’s pay what you want using discount codes).
