I'm pretty not tech savvy, so I have no idea what exactly I am dealing with, but on my Opera browser (should be latest, recently downloaded), I cannot login to Tumblr. I try, but it just redirects to the login page, no matter what I have in the url box, or what account I am using. I believe this happened on mobile once too, but I;m not sure how the problem would differ for a Windows user. Thanks.
