Can't login to sub-sites

Somewhere along the way, I lost the ability to login to my sub-sites. Whenever I try to login to the subsite, the login page will just refresh.

I've removed the following lines of my htaccess to no avail.

define('DOMAIN_CURRENT_SITE', 'novusjuris.com');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);
