Can't log back in tumblr.
Changed my browser, imported my data here. Things were already logged in, cool. So I logged out of tumblr, and when tried to log back in and pressed 'log in', I was redirected to the log in page instead of my dashboard. Password was ok, and CAN'T log back in UNLESS I import the data again from my old browser -which I want to uninstall-.
I don't know about Tumblr specifically as I don't use the site but generally you have to check a box somewhere to keep yourself logged in.
