Sometimes when I'm just doing normal posts, my account logs out. Even if I was logged in 5 seconds ago. It seems pretty random to me. I am on private browsing, but I'm still hoping there's a fix. Thanks!
If you don't have cookies enabled, it will log you out. I disabled my cookies one time and every time I refreshed the page, it logged me out. So, I would check if you have cookies enabled. Otherwise, it will keep happening.
I use incognito (in Chrome) and as long as an incognito window stays open, I stay logged in. That's often for days/weeks at a time (I never turn my computer off, but I live alone. The reason for incognito relates to history when people use my *other* computers)
