[Bug] Occasionally Logged Out of Forums for Short Period

From time to time, when I'm browsing the forums and commenting on posts, I will notice that the Post button will not work (as if it's broken). Upon copy/pasting the text and then refreshing the page, I'll notice that I've been logged out. Strange enough. When I try to log back in, if done within the next couple minutes or so, it will give me an error that my username or password is bad. My first time seeing this, I thought that someone had gotten hold of my account info somehow and started to send in a support ticket. But, before sending in the ticket, I went back to the forum and tried to sign in one more time and it worked flawlessly. Other times, I'll go to another tab to log in after a few minutes and it will have me already logged back in as if nothing had happened.

Today specifically, it happened twice when I tried to respond to this thread in Help and Support.

Note: At the page of commenting, before refreshed, it will show me as logged in.

Note: At the time of writing this, the same thread in Help and Support (after being refreshed) now shows that I am logged out, so I'll attached pictures of both this and the other tab.

EDIT: It's not allowing me to upload attachments. Upon pressing start upload, it remains at 0% even for 200kb size files. Has been fixed.
