WPMultisite Users on subdomain isn't logged in on main site
I have a problem. I run a blognetwork and when users login on their subdomain, they are not logged in on the whole "network". Meaning if they visit my mainsite.com they are not logged in, even though they logged in on the subdomain.
I use a Linode(VPS) server, and I suspect it might be some security settings here affecting it? As when I run a copy of the site on a shared hosting environment everything works fine.
Anybody know what could cause this?
