Login, but am not logged into the forum page?

TL;DR - I log in, move to forum tab and for some reason I'm no longer logged in. Cant post. Click login, sends me to profile page.

Hey,

So sometimes when I come to the site I go to the login tab and login in successfully, I can navigate to every tab except forum and it still shows me as logged in with a "logout" tab at the top. When I go to the forum page, that tab changes back to "login" again and if I click it it takes me to my general profile page with coin/point amounts and all that. If I try to post or contact a moderator it prompts me to login and sends me back to the general profile page and the loop continues.

What's up with that?

Same problem i have on my Chrome browser on android.

But works fine on chrome on desktop.

Idk wat the problem is, but it is annoying.

I've gotten it on both firefox and IE (work makes me use it). I feel like it might have something to do with the way it's setup as forum.warmane.com and all the other pages are warmane.com/*site* but I'm no net dev.
