text: Is it doing the thing for you where it says you're logged out, you go to log back in and then as soon as you do it just says you're logged back out again? If so the way I fixed it was to right click on the padlock (site secure) icon in the search bar, then click on "cookies and site data" and "manage cookies and site data", then deleted the site's cookies. That seemed to clear it up for me, and if it started happening again not too long afterwards I just did it again and it let me log in properly.
  Hope that helps you and maybe anyone else here who might be reading this but couldn't post because they were suffering from the same issue!
