Ubuntu 16, ee, WPMU subdomain + redis, problem is while I have access to wp admin (so I logged in), still on frontpage in sidebar I see Log in. And on the frontpage there is no admin bar. But when I go to site.com/wp-admin - I don't need to login... so front-end don't knows when I log in.
Tried with single wordpress - works fine, can repeat this bug only on multisite.
*checked again, problem seen only in Chrome with Multisite.
